| Abstract: | 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. |
