| 摘 要： | 分析线性调频信号加入锯齿波调频干扰的频谱特点和干扰效果,发现锯齿波调频干扰有产生虚假目标多、功耗低的特点,且在二维干扰的情况下能产生大面积多虚假目标,有效地对真实目标进行遮盖。并且分析了调制参数变化对干扰效果的影响,利用仿真实验验证了理论的正确性。

| Abstract: | After putting sawtooth frequency modulation jamming signal into LFM,the characteristics of jamming signal frequency and the jamming effect are analyzed.More fake targets with lower power can produced by this method.And it can produce many fake targets lay on large area under the condition of 2-D sawtooth frequency modulation,so that the real targets could be covered up effectively.The different results by the different modulation parameters are also analyzed,and simulation results prove the correctness of t... |
