Target imaging in strong ground clutter with stepped frequency signal

摘要

摘要: 該文主要研究了步進頻率信號體制下雷達對低空飛行目標在強地雜波背景下的成像處理方法，對步進頻率信號形式稍加改變以適應(yīng)成像前的預處理要求。對回波先采用一次相消處理濾除雜波，然后進行運動補償后再成像處理，仿真結(jié)果表明該成像方法有效。

Abstract: The imaging method with stepped frequency signal for low-altitude target in strong ground clutter is presented. The format of normal stepped frequency signal is modified slightly to satisfy ISAR imaging. The ground clutter is filtered through the one-order canceller, then after the motion compensation is completed, the images of the target are obtained. The validity of the imaging method is proven by simulation results.
