(This paper first introduces the radar simulator in recent years is widely available and the reasons for, and then on the target model, and the clutter model of airborne pulse Doppler radar, as under the spectrum distribution is analyzed. Then, to study radar signal simulation methods, with emphasis on the use of grid mapping method to the simulated clutter signal analysis and derivation, and use of this method, the Gaussian distribution of the Rayleigh spectrum of clutter, the radar echo signal simulation and analysis. Finally, for an airborne radar signal simulator system digital signal processor has been designed and analyzed.)
