摘　　要：以基于半导体泵浦固体激光器(DPSSL)的超窄脉冲激光引信技术为背景,对其接收机电路进行了研究。根据回波脉冲极窄的特点,分析对比了同相拓扑结构及反相拓扑结构的接收机电路的优缺点。基于理论分析,系统采用了反相拓扑结构的接收机电路,并通过Saber软件仿真分析,证明该电路具有良好的频率响应、相位裕度以及噪声小等特性,满足设计使用要求。In the background of ultra-narrow pulse laser fuse, this paper studies the receive circuit. According to the characteristics of the system, the noninverting amplifer and the inverting amplifer are compared, the characteristics of frequency and noise are analysed. Based on this theory, the inverting amplifer is used. Through Saber, it is proved that the circuit has the characteristics of good frequency re- sponse, good phase margin and low noise, and meets the design requirements.
