为从技术层面上提高反狙击能力，通过分析狙击步枪瞄准镜的反射特性，利用线阵CCD捕捉瞄准镜回波信号研制出主动式狙击手光电探测仪。介绍了探测仪的主要指标参数，并模拟实际使用环境验证了其探测效果。试验结果表明：在城市作战中狙击手通常伏击的距离为20m～200m，探测仪可准确探测微光瞄准镜及口径为32mm、40mm、42mm和50mm的白光瞄准镜，且不受镜子和手电筒凹面镜等反射体干扰，但对加装蜂窝板的瞄准镜,当距离大于80m后无法可靠探测。
Abstract
An active laser-illuminating sniper detector based on cat eye effect is developed. According to actual circumstances, some tests were conducted to verify the detection performance of the detector. Testing results show that night-vision sight and telescope sights with objective aperture diameters of 32mm, 40mm, 42mm and 50mm can be effectively detected by the detector in the range of 20m to 200m, and thermal weapon sight can not be detected either.
