| 摘 要： | 星载雷达飞行高度高,测绘带宽,因此地球曲率对成像的影响必须考虑;兼之卫星运行轨道偏离理想圆形,雷达离地面高度是个变数,这就使其运动补偿具有自己的特色。其次由于卫星运行速度极快,测绘带又宽,因此星载综合孔径雷达方位和距离模糊问题十分突出。再次,星载综合孔径雷达不满足聚焦深度条件,距离单元位移现象十分突出,必须专门加以校正等等。本文将从上述几方面,探讨星载综合孔径雷达总体设计的特点。

| Abstract: | The spaceborne synthetic aperture radar is an useful microwave remote sensor. It takes its advantage of high resolution and all weather, day and night mapping capability. So it is being getting wider and wider applications.In this paper, some aspects for designing a spaceborne SAR system, such as special mapping geometry, motion compensation, optimum ambiguity design and range cell migration correction are described and analized. |
