摘　　要：现有的靶场光电测试设备,虽然能够满足靶场测试中对大口径、高速动态目标的测试需求,但也具有一定局限性,如天幕靶测速设备为被动式测量原理,因此主动式测量能够扩展光电测试设备的应用领域。采用一字线型半导体激光器作为主动光源,APD器件作为光敏接收元件,通过锁相检测技术获取有效信号。设计了系统总体方案以及相关信号处理电路,通过理论分析、仿真和实验,验证了该方法的可行性,为靶场光电测试技术的深入应用奠定了一定的基础。Existing range optoelectronic test equipment, to some extent, can meet the range tests require- ments on large-caliber, high-speed dynamic target. Active measure can extend the optoelectronic test e- quipment field of application. Using linear semiconductor laser as the initiative light source, APD device as a photosensitive receiver components, we obtain effective signal, design overall system solutions and re- lated signal processing circuit through lock detection technology. Through theoretical analysis, simulation and experiment, we test the feasibility of the method which lays a certain foundation for depth application of the range optoelectronic testing techniques.
