摘　　要：从连续波多普勒引信对地面装甲目标的实测目标回波信号出发,应用MATLAB信号处理工具对其进行了时频综合分析,得出了在不同交会条件下的信号幅度频率变化特征,提出了一种无线电引信对目标碰炸优先作用的策略算法,以提高无线电近炸引信对目标的毁伤效能。在此基础上,设计了实用的数字信号处理器(DSP)系统电路来实现该策略,并探讨了软硬件设计中的关键问题。Based on the experimental result of some radio Doppler fuze attacking the subaerial armoring target, the echo signals are analyszed by using signal time domain and frequency domain and processed with MATLAB tools. The charicteristics of signal amplitude and frequency changing with time in diffrent encounter condition are gotten. The signal processing algorithm of impact burst prior for radio proximity fuze is put forward in order to destroy target more effectively. At last, a DSP system circuit for realizing impact burst prior is desiged and the key problems in the software and hardware design of the circuit are discussed.
