宽带雷达系统失真补偿信号的提取方法

Compensation Signal Extraction for Wideband Radar System Distortion

摘要: 系统失真将导致雷达距离像的展宽，并产生距离旁瓣。文中通过对实际ISAR试验雷达进行建模，对引起信号失真的机理进行了分析、研究，提出了补偿的方法，并对补偿方法进行了理论分析和仿真，针对实际的雷达系统，给出基于严格的脉冲压缩的系统失真补偿信号的提取方法，理论仿真和实际的雷达系统外场成像试验均验证了其正确性。

Abstract: The effect of system distortion on range profile of wide-band radar is analyzed , and the compensation method is discussed too. A new method of signal extraction for compensation of system distortion is put forward, and it is verified by theoretical simulation and results of radar imaging.
