摘　　要：激光近炸引信距离控制精度是导弹炸点控制的保证,是实现引战配合的前提。目前,激光引信距离控制精度测试主要利用"距离仿真"的光电法来实现,由于光电法存在最小启动距离且分辨力低,不能满足激光近炸引信测试要求。文中提出一种检测激光近炸引信测距能力与测距精度的方法。利用光在光纤中走过的光程来模拟激光回波走过的光程,通过调节直角棱镜组之间的距离来进行光程的精确调节,从而利用光在测试系统中走过的光程来模拟目标反射回波,实现精确的动态距离仿真。对距离仿真系统的最小测试距离和精度进行了分析。Range accuracy of laser proximity fuze is the key to control missile explosive point;it is the premise to realize the best match for fuze working and missile bursting.At present,one main method called'range simulation'is used to test the range accuracy.For the nearest starting range and lower range resolution,the method can not be used to test laser proximity fuze.Aiming at these problems,a method for the measurement of range testing ability and accuracy of laser proximity fuze is described.The optical path of the light transmitted in the fiber is used to simulate the laser echo wave,precise regulation of optical path can be achieved by adjusting the distances of the right angle prisms,thus target echo wave can be simulated by optical path in the test system,the precise dynamic ranging simulation can be achieved.The smallest testing distance and range accuracy are analyzed.
