摘要
En 中文
Although the bistatic forward-looking synthetic aperture radar (BFSAR) system can realize the imaging of the forward-looking area, the bistatic configuration brings new problems, such as synchronization errors. In this letter, the frequency synchronization error in the BFSAR system is discussed in detail, and its effects on target imaging are presented from theoretical analysis and simulation experiments. In addition, a refocusing algorithm based on the particle swarm optimization (PSO) method is proposed to compensate for the frequency synchronization error. Simulation results verify the feasibility of the proposed algorithm.
