摘　　要：为了解决小口径炮弹半主动式激光近炸引信在复杂环境中正确探测和识别目标的问题,研究了该引信的信号处理技术。运用模数混合的方法分析了系统信号预处理电路和数字信号处理电路设计方案。数字信号处理电路以单片微处理器为核心,体积小、功耗少、成本低。设计的信号处理系统较好地满足了小口径炮弹半主动式激光近炸引信的要求。In order to solve the problem of detecting and identifying targets in complex environmentv of the semi-active laser proximity fuze for a small caliber shell, the signal processing technique for the fuze is researched. The concepts of the system signal pre-processing circuit and digital signal processing circuit are analyzed with the analog-digital hybrid analysis. The single ehip microcomputer is used as the core of the digital signal processing circuit, for its small cubage, low power consumption and low cost, the signal processing system meets the need of the semi-active laser proximity fuze for a small caliber shell.
