| 摘 要： | 为提高连续波多普勒体制对空无线电引信的抗干扰性能,研究以频率特性实现炸点控制的引信系统.在分析空中目标的回波信号与干扰信号特征的基础上,利用两者频率特性的差异,设计了一种以微处理器为核心、实现频率定位的对空无线电引信信号处理电路,并对所设计电路进行了测试.实验结果表明:该引信信号处理电路在实现炸点控制功能的同时,能够有效抵抗两种干扰机的干扰,具有良好的抗干扰性能.

| Abstract: | To improve the anti-jamming ability of the continuous-wave Doppler radio fuze, based on the difference between the characteristics of echoes from a typical aerial target and those of the jamming wave, a kind of signal processing circuit is described, that is centered around a microprocessor unit and utilizes the frequency information of the echoes to control the proximity distance between the target and the projectile. Results of computer simulation and experimental tests show that the circuit can successfully control the proximity distance and has a better jamming resistance against the interference from two kinds of jammers. |
