| 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 |
