摘要
分析系统的幅相误差对高分辨SAR成像的影响,在此基础上提出利用预失真补偿技术对发射机的幅相误差进行补偿,给出一种利用FPGA实现预失真补偿的方法,经过飞机挂飞试验,取得高质量、高分辨率的SAR图像,通过试验证明此种补偿方法是可行的、有效的。
The influence of the amplitude and phase error on high-resolution SAR is analyzed in this thesis,Based on the analysis the pre-distortion method is proposed to compensate the amplitude and phase error of the transmitter,at last it is realized in FPGA.The high quality SAR image is acquired through the flight experimentation.It is proved that the method is valid.
