SAR卫星偏航导引补偿效果分析

The Analysis of the Compensation Effect of Yaw Steering for SAR

通过建立"SAR卫星—地球—目标点"几何模型,得到多普勒中心频率的精确值;简化模型,求得卫星的偏航导引规律;分析简化前后两模型,从而得出偏航导引的补偿效果。

A'SatelliteEarthTarget'geometric model is presented, and the exact Doppler centroid is obtained. On the basis of the simplified model, the yaw steering is found. From the analysis of the two models, a conclusion about the yaw steering's compensation effect is drawn.
