高空间分辨率的非成像型激光告警装置设计

Design of no imaging type laser warning device with high spatial resolution

为了在非成像型激光告警装置中获得来袭激光方位,使用半球体结构排布光电传感器。通过对光电传感器定位编号以及光强采集,基于激光来袭时的受光传感器空间坐标和激光强度,进行数学化建模,从而获得激光来袭方向。针对告警装置中噪声电流对该方法求解方位信息的影响,论证了该方法可得到的最小角度分辨率表达式,并为此方法设计了实际的可行方案。

For getting the coming laser direction in no imaging type laser warning device,a half-ball structure was applied to arrange the Photoelectric Sensors.with numbering all of the sensors and getting the light intensity information,based on the spatial coordinate of the sensors and the light intensity,built the mathematic model program to get the information of coming laser’s direction.Take the influence of noise to get the direction information,analysis the minimum angular resolution the method can get and design a feasible program for this method.
