摘　　要：针对设计的引信脉冲激光装定实际电路,主要分析了背景光和大气等干扰对引信脉冲激光装定系统性能的影响,采用双视场探测方法和数字相关检测技术对接收信号进行处理,并进行了实际电路改进。通过实验和分析计算,得出了电路改进前后的信噪比和信噪改善比,实验结果表明改进后的引信装定电路同时满足抗干扰和小型化要求,装定系统性能得到提高。According to the practical circuit, the interference influence on the fuze laser set system performance was analyzed. Techniques of dual receiving area detection and correlation detection were applied and realized in the improved circuit to alleviate or eliminate the interference, Experimental results shows that the improved fuze pulse laser set circuit has high signal-noise rate and signal-noise improved rate even while the fuze weak laser pulse signals submerges into noise. It meets the set system demand of anti-interference and small volume.
