摘要
为给SAR成像过程的运动补偿提供依据 ,通过建立卫星姿态的运动学方程和姿态的动力学方程 ,离散后获得卫星的姿态变化规律 ,进而分析卫星三姿态 (俯仰、横滚、偏航 )对星载SAR的Doppler参数的影响。最后得出卫星姿态运动对星载SAR的多普勒参数影响的仿真结果 ,从普遍意义上得出了卫星的姿态对星载SAR成像时的影响。
The change pattern of satellite attitude is obtained, by establishing the dynamics equation and kinematics equation and after discretization. Three satellite attitudes (roll, pitch, yaw) influencing the Doppler parameter of staellite-borne SAR are introduced. At last the simulation result is presented and the relation between the satellite attitude and the SAR image is given in a general sense.;
