The study of interference fringes in SAR distributed targets echo simulation

Interference fringes will be generated in SAR image when distributed targets´ echo data is simulated due to the uniform model of targets. The location and width of the fringes are related to the wavelength of signal, the incident angle of wave beam and the interval between adjacent targets. Further analysis about the influencing factors of the interference fringes is given in this paper and a suppression method is proposed at the end of this paper. Simulation results are presented according to the study.
