摘要
反欺骗抗干扰方法是通过在真实脉冲前加入欺骗脉冲,使敌方干扰机截获欺骗脉冲释放干扰,抑制干扰幅度,可以从源头上削弱干扰效果。欺骗脉冲的选择影响抑制干扰幅度的效果,因此通过分析单频、伪随机码调相和线性调频等不同调制方式的欺骗脉冲与真实脉冲的失配效果,给出欺骗脉冲选择策略。
The anti-deception technology can be used to active false targets of anti-interference. Deception impulse is send before real impulse in order to deceive the enemy jammer. Anti-deception method can reduce the effect of interference from the source. Deception pulse waveform selection affects the effect of anti-interfer-ence. The matching effects between the single carrier pulse,pseudo random code phase modulation pulse,chirp pulse and real pulse are analyzed. A strategy for deception pulse waveform selection is also given.
