【摘要】 为实现机载合成孔径雷达(SyntheticApertureRadar,简称SAR)实际回波数据中的运动目标聚焦成像,本文在用前置滤波法检测出运动目标的基础上,提出了利用目标子图像匹配方法来估计动目标的方位向速度,得到相应的运动目标聚焦参考函数,然后对运动目标进行聚焦成像,并给出了利用该方法得到的运动目标聚焦图像.成像结果表明,目标子图像匹配方法对动目标成像是有效的,易于工程实现,有实际应用价值.更多还原

【Abstract】 In order to achieve high quality imaging of moving targets in airborne SAR real data, a new azimuth velocity estimation method on sub-images match of moving target is proposed, which is based on moving targets detection results of pre-filter method. The method can compensate smear and azimuth displacement of a moving target, and it can produce a high-resolution moving target image. The availability and effectiveness of sub-images match method is illustrated by an example of airborne SAR real data processing.更多还原
