摘要
针对冲激引信传统的单距离门抽样积分相关检测进行门限判决的信号处理方法易造成引信在强杂波信号和有源干扰条件下误虚警的问题,提出了基于双距离门逻辑判决的冲激引信新型信号处理方法。该方法通过对传统冲激引信信号处理中的单距离门接收处理改为双取样距离门接收处理获取双路回波信号,然后利用冲激引信探测目标时,回波信号由远及近先后出现的逻辑特征进行双路回波信号能量判决及具有时序的逻辑判决。仿真和实测验证表明,基于双距离门逻辑判决的冲激引信信号处理方法可行,并具有较强抗有源干扰能力。
Aiming at the problem that the traditional signal processing method with single distance gate sampling integral correlation detection for threshold judgment of the impulse fuze was easy to cause false alarm under the condition of strong clutter signal and active jamming,a signal processing method for impulse fuze based on double-distance-gate logic decision was proposed.In this method,the dual sampling distance gate receiving process was used to obtain the double echo signal instead of single distance gate receiving process in the signal processing of traditional impulse fuze.When the impulse fuze detected the target,the dual echo signal energy determination and logical decision with time sequence were carried out by using the logic characteristics of the echo signal from far and near successively.Simulation and actual measurement showed that the signal processing method of impulse fuze based on double-distance-gate logic decision was feasible and had strong anti-active jamming capability.
