LASER THREAT WARNING SYSTEM AND METHOD

摘要

Laser threat warning system for detecting laser radiation transmitted by a threat source. The system filters noise and irrelevant detections using filtering mechanisms, while identifying and characterizing an incoming laser-based threat using threat identification mechanisms. The filtering mechanisms include an adjustable threshold mechanism, a correlation filtering mechanism, and a friendly fire avoidance mechanism. The threat identification mechanisms include a temporal mapping mechanism and a first arrival mechanism. The adjustable threshold mechanism filters noise signals by dynamically adjusting a noise threshold level based on detected ambient light conditions. The correlation filtering mechanism filters noise signals based on correlation criteria of the received radiation timing. The friendly fire avoidance mechanism filters radiation transmitted by a non-threat source. The temporal mapping mechanism identifies and characterizes the threat based on pulse mappings of the radiation. The first arrival mechanism determines the threat direction based on where the radiation arrived first among multiple laser detectors.
