An airborne SAR motion compensation algorithm based on array scanning and its implementation
一种基于相位扫描的机载SAR运动补偿算法及实现

Phased array radar is the main direction in the development of airborne SAR,and the motion compensation system is essential to the airborne SAR system. By deploying the coordinate mapping method,the target beam under the earth coordinate system is mapped into the antenna platform coordinate system and converted to the antenna array element phase shift which controls the beam. The airborne SAR motion compensation is then implemented. The algorithm is implemented by using DSP and FPGA. The experimental result...
