Automatic range containment system |
摘要 |
The present invention discloses an automatic range containment system for use in an electric/optical or electromagnetic active "radar" type sensor to discriminate against background obstructions within a sensor field of view. The system comprises an intrusion timer initiated by a signal received from a target sensor; a containment interval timer initiated by a turn-on pulse; a transmitter oscillator in combination with a clock generating pulses; a range containment timer initiated by the pulses; a range set-back timer in combination with a range gate and a gate; a range counter for counting and totalling a signal passed through the gate; and a digital-to-analog converter converting the signal from the range counter to the range containment timer providing a range control causing the system to reduce operational range if the background obstructions appear within the sensor's field of view.
