摘要
未来天基SAR向大场景区域、高分辨率方向发展 ,不仅要求监视大场景区域内的固定目标 ,而且要求能够同时对其中的运动目标进行指示。利用多个接收子阵并结合文中提出的空时处理方法 ,可同时实现大观测带。
In this paper a sub-array processing algorithm is proposed which requires conventional SAR antenna be divided into several sub-arrays with one sub-array transmitting and all sub-arrays receiving. The proposed algorithm can achieve both large swath width, high azimuth resolution SAR imaging of ground scene and ground moving target detection.
