摘要
用矢量法对星载SAR的Doppler参数进行分析。从卫星的地理位置出发 ,建立了卫星运动特性同空间的几何关系 ,推导出多普勒质心、多普勒斜率的矢量计算公式。给出了仿真结果 ,描述了卫星的运动状态同星载SAR成像质量的关系。
This paper introduces a vector method to estimate the Doppler parameter for spaceborne SAR. Beginning from the orbit of satellite, the relation between satellite movement and space position is investigated. The calculation formula of Doppler is presented. The simulation result is given. At last the relation between satellite movement and imaging quality of SAR is described.
