摘　　要：目前引信用激光接收机的探测精度和距离要求越来越高 ,系统的信噪比要求愈来愈大。前置放大器是影响整个系统信噪比的关键因素 ,本文在参考大量文献的基础上 ,设计一种适合引信用激光接收机的高信噪比低噪声前置放大器 ,并进行了计算、仿真、实验和分析 ,得到了满意的效果。The system's sign-to-noise is required better and better as the detection range and precison of the laser fuze receiver are higher and higher.The preamplifier's SNR is key factor in the laser proximity fuze system.Based on a great number of references,a high SNR,low noise preampliffer is designed for laser fuze receiver.By calculating,testing,simulating,analyzing,an approving result is obtained.
