Please explain the purpose of operation: |
To research develop and demonstrate Outdoor microwave intrusion sensors.
Raytheon Integrated Defense Systems (IDS) desire to us the is authority for research develop and demonstrate Outdoor microwave intrusion sensors shall be Southwest Microwave Model 300B or approved equal having a maximum range of 600 feet, and must also have field changeable antenna elements to allow the link to be operated at very short ranges up to 100 feet, and medium ranges up to 350 feet. The unit shall operate at a frequency of 10.525 GHz generated by a GaAs FET (Gallium Arsenide Field Effect Transistor) oscillator and must be certified by the Federal Communications Commission. The devices shall be bistatic and detect intrusion by sensing changes (increase and decrease) in the amplitude of the received signal. An automatic
gain control (AGC) circuit shall be incorporated which will adjust the receiver gain, as needed, for various distances from the transmitter and adjust the gain for changes in path loss, such as rain, snow, fog, etc. The range of the AGC circuit should be approximately 50 dB. The sensor shall be fully self-supervised and will alarm if component failure will cause the link to be incapable of detection. Four transmitter and receiver modulation frequencies shall be available to minimize interference between adjacent units. |
