研究了一种双条带成像处理方案。该模式是对环视成像模式的扩展,有效地提高了图像场景范围和成像处理效率。分析了双条带SAR成像处理的基本流程,针对雷达运动平台的实际运动情况,提出了一种满足图像分辨率和无缝拼接要求的系统实现方案以及相关系统参数的优化设计准则。借助点目标仿真和某型机载环视SAR外场试飞实测数据对该成像处理方案的有效性进行了充分地验证处理。 更多还原

【Abstract】 This paper studies the dual stripmap imaging program of the airborne SAR which carries a circular scanning antenna system that has the ability to map both sides of the radar’s flight path.This imaging mode is developed from the circular-scanning mode,which effectively improves the image size and the imaging efficiency.The basic imaging procedure is firstly analyzed,then the implementation as well as the rules of choosing the system parameters to fulfill the image resolution and the seamless mosa... 更多还原
