针对宽带成像雷达的工作方式和特点，提出了一种采用DRFM对宽带高分辨成像雷达的新干扰方法。首先推导了DRFM转发信号的数学模型，阐述了宽带雷达一维成像的基本原理。在此基础上提出了一种采用移频调制对宽带雷达一维成像进行转发式干扰的方法。该方法不但能有效地破坏雷达对真目标的一维成像，并可形成虚假目标一维像。通过仿真并结合实测数据，对该方法进行了验证，结果表明了这种方法的可行性。该方法可对一维和二维成像雷达进行干扰。

According to the operation mode of wide-band radar, DRFM is proposed to use for jamming wide-band radar imaging. The model of false target is firstly derived and the principle of 1-D imaging is explained. A new method using frequency modulation is presented to jam radar range imaging. The method can destroy radar imaging in range and can form false range profiles. Combined with real measured radar data, numerical simulation are used to test the method. Results show that the new method is feasible for jamming 1-D and 2-D radar imaging.
