A unique continuously variable Range Cutoff (RCO) circuit allows maximum detection range to be established independently of object size, thereby eliminating alarms caused by large objects beyond the desired detection range. Model 380 is also equipped with Zero Range Suppression (ZRS) circuitry that reduces sensitivity to small objects very close to the transceiver so that alarms due to rain or vibration are minimized. Model 380 includes synchronization and addressing circuitry that enables simultaneous operation of up to 16 units without mutual interference. The Model 380 is also built with staggered RF frequencies (Channel A and B) to help minimize mutual interference. Model 380 may be mounted to a variety of posts or wall structures by means of its universal-mounting bracket. A military style multi-pin connector, at the rear of the transceiver housing, permits remote monitoring and diagnostics of critical system parameters. OPERATION_________________________________________________________________ Model 380 includes both transmitter and receiver in a single enclosure. The transmitter radiates microwave energy that is reflected back into the receiver by objects within the detection zone. The observed detection zone is established by two controls - Sensitivity and Range. Figure 1A shows the zone of detection (horizontal pattern) for an upright man when Model 380 is mounted 2.5 feet (.75 meters) above smooth earth with its beam oriented parallel to the ground. The Range control adjusts the maximum range of the system and the Sensitivity control primarily adjusts the width. Figure 1B shows the vertical pattern for the same configuration, note that the detection zone does not extend into the small area immediately under Model 380. This area varies with the Sensitivity setting as shown in Figure 2. In order to provide uninterrupted detection of a man walking or crawling on his hands and knees, an additional unit must provide overlap protection such as shown in Figure 3. Detection of a man crawling "commando-style" may require additional overlap or special site preparation. Sensitivity should always be adjusted to the absolute lowest setting that will meet site security requirements. Excessively high sensitivity may cause nuisance alarms from high grass, small birds or windblown debris in the detection zone. Model 380 responds to any motion within the detection zone.

TEST PROCEDURE AND REPORT CONDUCTED AND RADIATED EMISSIONS UNLICENSED INTENTIONAL RADIATOR SOUTHWEST MICROWAVE MODEL 380 31 MARCH 2003 INTRODUCTION This procedure and report was prepared to insure compliance with the requirements of part 15.245 of the Federal Communications Rules and Regulations regarding unlicensed intentional radiators. The procedures outlined herein are based on the October 1, 2001 revision of the Federal Communications Commission Rules and Regulations, Parts 2 and 15. The measurements made herein were performed on a preproduction model of the equipment specified and is considered representative of all production units of this series. The product referenced in this document is a microwave transceiver operating within the frequency band of 24.075 to 24.175 GHz. It is a shorter-range version of the Southwest Microwave Model 385 that was certified under file number 31010/EQU 4-3-3 dated August 13, 1991. All aspects of the two sensors are electrically identical except that model 380 has a lower gain antenna. The Doppler sensor is intended to operate as an outdoor security system and therefore must be certified as an intentional radiator. Because of the low powers involved, RF harmonic measurements were performed directly on the transmitter using a waveguide test set-up and then repeated with an antenna installed on the 3-meter test site. All microwave testing was performed at the Southwest Microwave test site, documentation for which has been filed with the Federal Communications Commission. M. Flom and Associates, Chandler, AZ performed radiation tests per part 15.209 of the commission’s rules. This product utilizes a 4.2-inch diameter parabolic antenna, having a gain of approximately 22.4 dB and a beamwidth of 8.0 degrees (-3 dB) at 24.125 GHz. The modulation signal is comprised of a one-microsecond pulse train operating at a 32-kilohertz repetition rate resulting in a 3.2 percent duty cycle. Alternate pulses are shifted in frequency by approximately 615 kilohertz. BLOCK DIAGRAM Referring to the block diagram shown below, all timing functions are derived from the master clock which is contained within the phase locked loop and is operating at a frequency of 1.024 MHz. The clock is divided down to 1 kHz and coupled to the phase comparator of the phase locked loop. If the system is operated in the master mode the oscillator is free running and provides a 1 kHz clock at the master output terminals. This RS 422 master output can be used to sync up to 16 other units together, providing a unique address to each so that interference between sensors is eliminated. The address is selected by means of a binary switch located in each sensor. The phase-lock loop output is connected to a binary ripple counter which provides a 1 microsecond pulse at a 32 kHz repetition rate and a 32 kHz square wave which is connected to a divide by 2 circuit resulting in two channels at 16 kHz of opposite phase. The one-microsecond pulse is connected to oscillator drive circuit, which provides a minimal voltage change resulting in a small frequency shift on alternate pulses (approximately 615 kHz). The transmitted signal is therefore a continuous pulse train of 1- microsecond pulses at a 32 kHz repetition frequency with alternate pulses shifted by 615 kHz. A certain portion of the transmitted signal is coupled to a detector diode where the pulse envelope is detected, amplified and connected to a leading edge detector circuit. The output of this circuit is a narrow sampling pulse that is positioned from the leading edge in time by means of a user accessible range-cutoff potentiometer. The range cutoff feature prevents signals from being processed beyond the time it takes the RF pulses to intercept the target and return. The receiver channels are alternately switched at a 16 kHz rate coincident with the Fa and Fb frequencies. The two-frequency approach provides Doppler signals whose phase is proportional to range. The sampled Doppler output of each channel is then connected to a difference amplifier, the output of which provides a signal whose amplitude is proportional to the phase difference between the two Doppler signals. The purpose of this circuit is to cancel the effects of rain on the radome. Rain running down the radome causes Doppler signals that are in phase because of the close proximity to the transmitter and are essentially cancelled. The Doppler output of the difference amplifier is amplified after filtering and then connected to a comparator circuit that provides an alarm if the signal amplitude exceeds either threshold. 4 BIT COMP ADDR PLL CTR MASTER OUTPUT SLAVE INPUT 1.0 uSec AMP AMP + - SENS VL ALARM CKTS THRESHOLD LOW-PASS FILTER RCO TIMING RANGE FbFa TX OSC VCO DRIVER Fc FcFd + - LOCK S1 RELAY TB1-6 TB1-7 TB1-8 TB1-4 TB1-5 N.O.
