一种多点非匀速旋转的ISAR雷达干扰方法

An ISAR Radar Jamming Algorithm Based on Multi-point Non-uniform Rotation

根据目标旋转微动产生的微多普勒能影响逆合成孔径雷达(ISAR)成像的特点,提出了一种多点非匀速旋转的微动干扰算法。通过对截获的雷达信号进行调制,形成多点非均匀多普勒调制的ISAR图像微动干扰,该干扰样式不仅能够实现ISAR图像干扰,还使得ISAR图像的微动特性难以提取,影响ISAR识别。仿真实验验证了所提算法的有效性。

According to the characteristic that the micro-Doppler produced by micro-motion of target rotation can affect inverse synthetic aperture radar(ISAR) imaging, a micro-motion jamming algorithm of multi-point non-uniform rotation is presented.By modulating the intercepted radar signals, this paper forms the micro-motion jamming of ISAR images with multi-point non-uniform Doppler modulation.The jamming mode can not only realize the ISAR image jamming, but also make it difficult to extract the micro-motion characteristic of ISAR images, which will affect ISAR recognition.Simulation experiments verify the effectiveness of the proposed algorithm.
