| Abstract: | Phased array radar is the main direction of airborne SAR, and the motion compensation system is essential to the airborne SAR system. According to the phased array theory, a motion compensation algorithm using phase scanning to control beam is presented. The algorithm is implemented by using ADSP-TS201S and FPGA. It was tested in an airborne SAR and got a good experiment result. |
