| 摘 要： | 通过对SAR卫星运动的分析,推导出椭圆轨道星载SAR考虑姿态角（横滚、俯仰、偏航）的多普勒性质的表达式.讨论了卫星姿态角对多普勒性质的影响.并就卫星姿态对星载SAR多普勒参数的影响进行了仿真试验,理论和仿真结果表明卫星姿态对星载SAR多普勒参数有较大的影响.

| Abstract: | Through the analysis of the movement of SAR satellite,the expressions of Doppler properties of an elliptic orbit space-borne SAR interms of its aspects(roll,pitch,yaw) are derived.The effects of the aspect on Doppler properties are given further.The simulations of the effects of the aspect to spaceborne SAR Doppler properties are performed.The theoretical and simulation results show that the aspect has significant effects on spaceborne SAR Doppler parameter. |
