| 摘 要： | 该文主要研究了步进频率信号体制下雷达对低空飞行目标在强地杂波背景下的成像处理方法，对步进频率信号形式稍加改变以适应成像前的预处理要求。对回波先采用一次相消处理滤除杂波，然后进行运动补偿后再成像处理，仿真结果表明该成像方法有效。

| 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. |
