GENERAL INTRODUCTION The Echomax Active-XS-Dual Band Radar Target Enhancer (RTE) is designed to respond to interrogating both X (9.3 - 9.5 GHz) and S band radar (2.9 - 3.1 GHz) by receiving a transmitted pulse, amplifying and re - t r a n s m i t t i n g the pulse back to the radar at the same frequency with minimum delay, thereby improving the radar detection range and visibility of small targets. It will not enhance significantly vessels with large radar cross section. The Active-XS-Dual Band Radar Target Enhancer is suitable for all vessels up to 150 gross tonnage. SOLAS V Regulation 19 2.1.7 states (Radar reflector):All ships irrespective of size shall have: if less than 150 gross tonnage and if practicable, a radar reflector, or other means to enable detection by ships navigating by radar at both 9 GHz (XBand) and 3 GHz. (S Band). The Active-XS-Dual Band Radar Target Enhancer will typically enhance the RCS (radar cross section) of vessels up to 25M in length. For small craft/rigid inflatables improvements will start to be seen at around 1-2 miles extending to 8-10 miles or more depending on prevailing conditions. The response of the RTE will vary according to range, RTE and radar height above sea level, radar power and condition. Poor weather, sea state and precipitation will greatly reduce the response. IMPORTANT The fitting of the Active-XS-Dual Band RTE does not exclude you from exercising safe navigational judgement for your vessel under the International Regulations for the Prevention of Collisions at Sea and to keep a proper look out at all times LICENSING REQUIREMENTS Many countries and administrations require a ships radio license or modification of your existing ships radio licence before the Active-XS can be used for maritime use. Contact your local administration for details. ECHOMAX ACTIVE-XS COMPONENTS, CONSTRUCTION, use and installation If you are not able to safely install the unit yourself you are advised to seek the services of a competent person or company to install the RTE. COMPONENTS Echomax Active-XS mast head radome fitted with 24 meters of 3 core cable Control box Operation manual RADOME FITTING The antenna has provisions in the base for a 1 inch -14 NF female thread mast fitting or deck mount bracket. Plastic mounts should not be used. To ensure a permanent fixing ‘LOCTITE’ or PTFE or plumbers tape should be used and the RTE must be screwed down tightly. Care must be taken to ensure that as the RTE is tightened on the base the cable is allowed to turn freely. For mast fitting the radome must be fitted vertically as high as possible. The receive/ transmit antennas positioned 70mm from the base of the radome must have a clear 360 degree azimuth. It should be fitted at least 6 inches/150mm from the mast on the offset bracket. It should not be fitted on a back stay or where its vision is obscured or is close to any metal object otherwise performance could be significantly impaired. The radome unit must never be painted as this will seriously impair performance. The radome must not be fitted in or close to the vessels radar vertical or horizontal transmitting beam as this may seriously d a m a g ethe PCB. The RTE should be fitted above the radar. It is possible to shorten the cable or extend by a further 25 meters without affecting thep e rf o rm a n c e using extension cable rated at 3A at 300V. ECHOMAX CONTROL BOX for surface fitting or flush mount with optional new flush mount kit Use and wiring instructions The control box must be fitted internally as it is not waterproof and can be wired from the base or back as required. A 12v fused or circuit breaker supply of 3-5A is required. The control box has a quadruple alarm facility. Once the red power switch is turned on the unit is in the quiescent mode and will consume up to 23mA. When interrogated by an X Band radar the green LED light will flash every 2.4 seconds. If the flash lengthens then this indicates that more than one radar is painting the antenna. If painted by a high speed radar which rotates every 1.5 seconds then the LED light will flash quicker. When painted by an S Band radar the yellow light will flash. It should be borne in mind that vessels with S Band radar are very large and in most cases over 3000GT and can neither stop nor change course quickly. Turning on the green switch will mobilize the i n t e rnal buzzer, which is set to actuate at appro x i m a t e l y half a second intervals. The control box also has facilities for a 8A external volt free alarm. THISISNOT APOWERSOURCE and must be initialised as shown in the wiring diagram. The control box has an externally replaceable 2 Amp fuse and is surge and cross polarity protected. All radars emit irregular vertical side lodes (spikes) and should the Active-XS be installed in the path of a spike it will think that it is being painted by another ships radar. Movement of the Active-XSradome to another position may remedy this, if not, the ships radar will need to be switched off. Identical radar may have a different side lobe pattern. Ac t i v e-XS-D u a lBand Radar Target Enhancer Ac t i v e-XS-D u a lBand Radar Target Enhancer RTECONNECTIONS The diagrams show the correct wiring installation PERFORMANCE CHECK As the RCS of your vessel may exceed the RCS of the RTE, the trial is best carried out at 0.5 nm as the target can be easily identified. The range should then be increased at intervals of 0.5 nm and the RTE switched on and off noting the change in response. As the range increases the bare target will not be seen and whilst moving the RTE is left on so that the test target can be seen at all times. This is important in busy waters to …

Federal Communications CommissionDA 10-2438 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of OCEAN SIGNAL LTD. Request for Waiver to Allow Certification and Use of a Dual Band Marine Radar Target Enhancer ) ) ) ) ) ) WT Docket No. 10-160 ORDER Adopted: December 29, 2010Released: December 30, 2010 By the Deputy Chief, Mobility Division, Wireless Telecommunications Bureau: 1.Introduction. This Ordergrants a request for waiver to permit the certification and use of maritime equipment that is not authorized by Part 80 of the Commission’s Rules. On June 21, 2010, Ocean Signal Ltd. (Ocean Signal), on behalf of Aquamate Products Ltd., filed a request for waiver of Section 80.375(d) of the Commission's Rules 1 to permit equipment certification and use of itsdual band, S- band (2.9-3.1 GHz) and X-band (9.3-9.5 GHz), Radar Target Enhancer (RTE). 2 For reasons set forth below, we grant Ocean Signal’s request for waiver. 2.Background.RTEs are used on small vessels to increase their detection and visibility to radarby receiving a radar signal from a passing vessel, amplifying the signal, and re-transmitting a stronger return signal. Chapter V of the International Convention for the Safety of Life at Sea (SOLAS) requires ships of less than 150 tons, if practicable, to have “a radar reflector, or other means, to enable detection by ships navigating by radar at both 9 and 3 GHz,” 3 but Section 80.375(d), which governs ship and shore radar and transponder frequencies above 2400 MHz, does not provide for the use of RTEs. Ocean Signal therefore seeks a waiver of Section 80.375(d). It states that its RTE will advance marine navigation safety by enhancing radar detection and visibility of small vessels. 4 3.Performance standards for radar reflectors have been issued by the International Maritime Organization (IMO) in Resolution MSC.164(78), 5 the International Organization for Standardization (ISO) in ISO 8729-2, 6 and the International Telecommunications Union (ITU) in ITU-R M.1176. 7 Except for the ISO standard, these standards are recognized in Chapter V of the SOLAS Convention carriage and 1 47 C.F.R. § 80.375(d). 2 Request for Waiver (filed June 21, 2010) (Waiver Request). On August 9, 2010, we sought comment on Ocean Signal’s waiver request. See Wireless Telecommunications Bureau Seeks Comment on Request by Ocean Signal Ltd. for Waiver to AllowCertification and Use of a Dual Band Marine Radar Target Enhancer, Public Notice, 25 FCC Rcd 10696 (WTB MD 2010). No comments were received. 3 SeeConsolidated Text to the International Convention for the Safety of Life at Sea (SOLAS), 2009, Chpt. V, Regulation 19.2.1.7. 4 See Waiver Request at 1. 5 IMO Resolution MSC.164(78), “Revised performance standards for Radar Reflectors,” adopted May 17, 2004. 6 ISO 8729-2, “Ship and marine technology –Marine radar reflectors –Part 2: Active type” (May 2009). 7 ITU-R M.1176, “Technical parameters of radar target enhancers” (1995). Federal Communications CommissionDA 10-2438 2 performance standard regulations. 8 4.Ocean Signal states thatits RTE meets these standards, with one exception. ITU-R M.1176 requires a minimum gain of 50 dB for both S-band and X-band RTEs. Ocean Signal argues, however, that this constitutes a discrepancy between ITU-R M.1176 and Resolution MSC.164(78), because requiring 50 dB gain for S-band RTEs results in an antenna that is both too large to be deployed on smaller vessels, and reflectsthe radar signal a significantly longer distance than required by Resolution MSC.164(78). 9 5.Discussion.Section 1.925(b)(3) of the Commission's Rules provides that we may grant a waiver if it is shown that (a) the underlying purpose of the rule(s) wouldnot be served or would be frustrated by application to the instant case, and grant of the requested waiver would be in the public interest; or (b) in light of unique or unusual circumstances, application of the rule(s) would be inequitable, unduly burdensome, or contrary to the public interest, or the applicant has no reasonable alternative. 10 We conclude that the waiver of the Commission’s Rules requested by Ocean Signal is warranted under the circumstances presented. Specifically, we conclude that the underlying purpose of the subject Commission rule would not be served by application to the instant case, and grant of the requested waiver would be in the public interest. RTEs provide small vessels increased detection and visibility to radar received from a passing vessel. Use of RTEs will serve the underlying purpose of Section 80.375, which is to authorize operation of ship and shore radar stations, and will serve the public interest by enhancing maritime safety. 6.Finally, we agree with Ocean Signal that its RTE should not be required to meet the all of the technical standards in ITU-R M.1176, at least with respect to non-SOLAS vessels. We believe that requiring a minimum gain of 50 dB for the S-band would render the device unsuitable for its intended use by necessitating an antenna that is too large to be practical for small, non-SOLAS, vessels. Instead, Ocean Signal’s RTE shall be required to meet the S-band technical standards in IMO Resolution MSC 164(87) in lieu of the minimum gain for the S-band required by the ITU standard for non-SOLAS vessels. 11 The device must meet all other applicable IMO, ISO, and ITU requirements. 7.All applications for equipment authorization pursuant to this waiver must be submitted to the FCC Laboratory. A copy of this Ordershall be submitted with the equipment authorization application. 8.Accordingly, IT IS ORDERED, pursuant to Sections 4(i) and 303(i) of the Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i), 303(i), and Section 1.925 of the Commission's Rules, 47 C.F.R. § 1.925, that the Request for Waiver of Section 80.375(d) of the Commission’s Rules, 47 C.F.R. § 80.375(d), filed by Ocean Signal Ltd. on June 21, 2010, IS GRANTED to the extent specified herein. 8 See Consolidated …

The task was performed under contract number COM-ICS-10-164-KG for Coverise Ltd. The equipment under test (EUT) has been tested against sections of active radar reflector RCS specification ISO 8729-2 [1] and R&TTE specification ETSI EN 302 752 [2]. The RCS and spurious emissions measurement results are summarised in a table in the main body of the report with the full results detailed in Annex A for comparison against the specifications.

Figure 1 ACTIVE-XS dual band RTE mounted in the anechoic chamber Commercial in Confidence QINETIQ/TS/SDS/CR1002449 Page 7 Commercial in Confidence 3 Measurement Techniques 3.1 Radar Cross Section (RCS) The S and X band RCS measurements were carried out in the anechoic chamber at QinetiQ Funtington, figure 2. The chamber consists of a 15m long, 6m wide and 5m high screened room clad with radar absorbent material (RAM). The radar transmit and receive horns are mounted side by side and are positioned in the middle of the wall at one end of the chamber. At the other end, the target is positioned on a low RCS mount at the same height as the horns and this sits on an azimuth-over-elevation positioner which is screened by a small RAM wall. Figure 2 QinetiQ Funtington’s anechoic chamber with 300mm sphere being tested The facility uses a HP8530 vector network analyser with a HP8511A frequency converter unit as the calibrated radar. The system is computer controlled and the positioner data is synchronised with the measured RCS, which is plotted in real time. The RCS system is calibrated using a 300mm-diameter sphere with an RCS of -11.4dBm 2 (0.072m 2 ). The background clutter from the chamber is suppressed using an automated background subtraction method measured when the chamber is empty. For the main RCS testing the device was tested below its saturation level. For the saturated power tests at 0 ̊ elevation the RCS was tested …
