| Abstract: | The phase synchronization between transmitter and receiver is a key problem to the bistatic synthetic aperture radar(BiSAR)system.Using a phase locked loop(PLL)receiver is one of possible methods to realize the phase synchronization of a BiSAR system.The performance of a PLL receiver in the case of aircraft motion error is discussed,and the influence of PLL phase error on imaging of BiSAR system is analyzed in this paper.Finally,the results of computer simulation are presented. |
