摘　　要：针对传统野外使用的光电探测靶存在高空测量时靶面小、探测灵敏度低等不足,结合探测靶的工作特点并根据光度学理论,分析光电探测靶的光学设计参数对探测性能的影响;选用阵列光电探测器为探测靶的光电接收器件,采用离焦技术,消除阵列光电探测器存在的探测盲区,分析采用矩形光阑方案,削弱背景光大幅度变化引起的自激现象,提高与稳定光电探测靶的探测性能。The traditional optic-electric detecting target board used in the field has the disadvantages of small target surface and low detection sensitivity at high-altitude. Based on the operational features of the optic-electric detecting target board and the theory of optics, we analyzed the influence of designed optical parameters of the target board on detection performance. Array optic-electric detector was used as the optic-electric receiver in the detecting target board, and deviating focus technology was adopted to eliminate detection blind area of array optic-electric detector. Rectangular diaphragm was used for depressing the influence of background light, and thus to improve and stabilize the detection performance of the optic-electric detecting target board.
