Report : RF Duty Cycle of CEL Microwave Sensor Prepared For: ITC Prepared by: CEL Date: 07/07/05 Connaught Electronics Ltd. IDA INDUSTRIAL ESTATE, DUNMORE ROAD, TUAM, CO. GALWAY, IRELAND. Telephone: +353 93 25128 Fax: +353 93 25133 1 Scope This document details the RF duty cycle of CEL’s pulsed microwave sensor. 2 Duty Cycle Determination In order to determine the RF duty cycle, the PRF frequency and the oscillator on-time of the microwave sensor are measured and using these the duty cycle is calculated. 2.1 PRF Oscillator Period The pulsed microwave oscillator is turned on/off by the PRF (Pulse Repetition Frequency) oscillator. The pulse repetition frequency is 1.5MHz. (see fig.1 below). PRF = 1.5MHz Oscillator period = 682ns fig.1 2.2 RF pulse width determination: The range of the SDR is 85cm. Thus using the mathematical formula for RF waves the pulse width can be determined: Pulse width = (Range*2)/(3x10 8 ) In the case of CEL’s SDR sensor: Pulse width = 1.7/(3x10 8 ) = 5.66ns 2.3 Duty Cycle Calculation Duty Cycle (%) = RF Pulse Duration/PRF Oscillation Period = (5.66ns/682ns) * 100 = 0.83 %

Operational Description

FCC ID: (LQN2923 & LQN2924) Frame 1 of 7 TECHNICAL FILE FOR BENTLEY_ MICROWAVE SENSOR CEL P/N: 902923 902924 Connaught Electronics Ltd. IDA INDUSTRIAL ESTATE, DUNMORE ROAD, TUAM, CO. GALWAY, IRELAND. Telephone: +353 93 25128 Fax: +353 93 25133 A/C Fax: +353 93 24047 [email protected] www.cel-europe.com FCC ID: (LQN2923 & LQN2924) Frame 2 of 7 1.0 Introduction This is a Technical File for BENTLEY Microwave sensor electronics supplied by CEL to BENTLEY. 1.1 Theory of Operation The vehicle passenger compartment protection system operates as a microwave based motion detection sensor. The sensor detects motion within a set surveillance hemisphere and an alarm signal is sent to the Ground Module. The sensor works on the Doppler principle. The transmit antenna transmits an electro-magnetic field into the vehicle. The receive antenna accepts reflections from moving targets and the resulting signals are filtered and amplified before being sent to the microcontroller for evaluation. The range is adjustable in software. Thus, the range can always be adjusted to fill the vehicle interior, in relation to the shortest distance between the Microwave sensor and the windscreen or vehicle roof (the limits of the vehicle passenger compartment). In this way, a hemispherical field is generated within the vehicle as the area to be monitored. If a large enough change in analog signal amplitude occurs, an analysis of the signal evaluation is started. The microcontroller contains a software algorithm that determines if the signal is a genuine movement or a spurious signal. If this analysis detects significant characteristics of a movement, an alarm is issued to the ground module via the INRS wire line.

When sensitized, it is woken by an interrupt on the ST line. The sensitization period for the microwave sensor module, to full functionality, is 30 seconds. The complete alarm system is likewise ready for operation 30 seconds after sensitization of the DWA (anti-theft warning system). The microwave sensor module operates in impulse mode : that is, like a radar impulse system. An impulse is emitted for a brief period and the reflected signal received is amplified and evaluated. Because the module operates with a very low transmission output, more powerful external frequencies can connect with the receiver side of the device and cause false alarms. The reflected signal is checked in parallel with a suitable EMC protection switching unit and any foreign frequencies are filtered out. Any real movement in the detection area is recognized by a change in the reflection sample. The module emits a pulsed signal and delays this in accordance with the detection range required. This delayed impulse then controls the receiver section. Only after this delay time is the receiver section opened for a short period, when an associated signal pattern is stored. In reality, the detection range corresponds with a spherical "shell" having a width of ca. 5cm. The signal is stored in terms of amplitude and pattern and is compared with the next signal which is received. 1.3 Physical Construction Housing: LENGTH: 70mm, WIDTH: 63mm, HEIGHT: 29.5mm FCC ID: (LQN2923 & LQN2924) Frame 4 of 7 PCB: Two layer, Board material FR4 Layer 1: Components and signal tracks Layer 2: Ground plane Connector Detail: • 4 way Amp part Number: 4-1393472-9.
