摘要:

ISAR 的干扰措施通常可分为压制干扰和欺骗干扰两类。由于 ISAR 在进行信号处理时具有较高的处理增益,对噪声压制干扰的干扰功率提出了较高的要求。在欺骗式干扰方面,目前主要采用数字图像合成技术,对截获的 ISAR 脉冲信号进行幅度调制和相位调制,然后再发射出去,从而在雷达接收端形成虚假目标像。文中对ISAR对压制干扰和欺骗干扰做了分析,并就噪声调频干扰和欺骗干扰做了Matlab仿真。仿真结果表明,噪声压制干扰需要较高的干扰功率。

关键词: 逆合成孔径雷达, 噪声调频干扰, 欺骗干扰, Matlab仿真

Abstract:

The interference measures of ISAR are usually divided into suppressive jamming and deception jamming.The power of suppressive jamming is supposed to be high because the gain is high when the radar processes the signal.The deception jamming mainly uses Digital Image Synthesis (DIS),which modulates the amplitude and phase of the signal-intercepted and then forms the false target.This paper makes a brief analysis of suppress interference and deception jamming.The Matlab simulation shows that suppressive jamming has higher jamming power.

Key words: inverse synthetic aperture radar;noise FM jamming;deception jamming;Matlab
