摘要: |
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。 |
关键词: 几何模型 偏航导引规律 补偿效果 |

Abstract: |
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. |
Keywords: geometric model yaw steering compensation effect |
