摘　　要：信号处理器是跳频引信的一个核心电路。为了提高引信的可靠性,检测精度,抗干扰能力,必须考虑设计合理的信号处理器。文中充分利用了目标信号的频率、幅度和增幅速率这三个特征量,设计出具有幅度检测、增幅速率检测、带外干扰信号检测的信号处理器。理论分析和试验结果表明,该信号处理器能够使引信对目标信号的识别能力和抗干扰能力有较大提高。The signal processor is a core circuit of a frequency-hopping fuze. In order to improve the reliability, detection precision, and anti-jamming performance of a fuze, it is necessary to design a appreciate signal processor. In this paper, a signal processor, which can measure frequency, amplitude and amplitude-increasing velocity, is contrived by making full use of these three characteristic parameters. According to the theory analysis and the test results, the signal processor can enhance the target signal recognition capability and anti-jamming performance of a fuze greatly.
