Detecting and Warning System Design of Laser Attacking Direction
For detecting laser attacking direction from enemy, we develop a warning system which can detect the direction of coming laser pulse. This system is composed of optical module, signal processing module, and display module. Its detection range is 0° to 360° on the horizontal direction and 0° to 90° on the vertical direction, and angle identification is 30°. Laser pulse wave length of 0.85, 1.06 and 1.54 μm, pulse width no less than 10 ns, can be distinguished. The floor of detection power is 1 mW/cm2, the detection probability is more than 98 percent, and it realizes real-time warning. Compared with former devices, its angle identification is developed, and the floor of detection power is 5~10 km and meets the need of detected distance.
