针对传统毫米波近炸引信数字信号处理器距离分辨率不高、处理时间长、实时性差的问题，设计了数字化信号处理器。该信号处理器对中频回波信号进行数字化采样(AD)，然后对采样数字信号进行脉压处理，利用动目标检测(MTD)技术对确定炸高的脉压数据进行相干积累从而得到该高度的目标多普勒信息，并根据新的自适应检测准则对目标进行检测。外场试验数据处理结果表明：该系统能稳定、实时地输出起爆信号，起爆高度符合系统指标要求，并且该信号处理器还具有很好的速度适应性。

The traditional microwave fuze has low detective accuracy and poor resolution,and flexibility is poor. a proximity millimeter wave fuze with digital signal processor was designed to solve the problem.The echo pulse signal was compressed,and target Doppler information was obtained by MTD processing.At last,the target was detected according to the adaptive detection criteria proposed in this paper.Experimental data processing re-sults showed that the system could output a stable and real-time detonation signal on required height,at the same time,the systems also had a good adaptability for different target and speed.
