摘要
应答式干扰机可有效干扰主动雷达导引头,使其偏离真实目标,降低杀伤概率。为了对抗应答式干扰,分析了掩护脉冲对导引头信号处理的影响。并在不影响导引头正常工作的前提下,针对工作于短存储模式下的应答式干扰机,仿真分析了采取增量消除前后掩护脉冲的抗干扰效果。仿真结果表明,对于不采用增量消除技术的干扰机,可在探测脉冲之前设计一个宽脉冲掩护信号或脉宽相同、频率不同的掩护信号;而对于采用增量消除的干扰机,只要掩护脉冲脉宽足够大即可达到抗干扰的目的。
Transponder jamming can efficiently decoy active radar seeker, making it miss the real goal. In order to suppress the jamming, effects of protecting signal on the seeker＇s signal processing are discussed. Based on the assumption that the seeker works well, simulations of the anti-jamming effects of incremental elimination taken before and after are done under the model of short storage. The results show that if the jammer doesn＇t adopt incremental elimination, a broader pulse or a pulse in the same width but different frequency with the real one can be designed before the detecting signal. As for the jammer with the technique of incremental elimination, however, only by increasing the pulse width can effectively protect the detecting pulses.
