System performance simulation of an UWB FLGPSAR based on Matlab/Simulink

The simulation system of an ultra-wideband forward looking ground penetrating synthetic aperture radar (FLGPSAR) is analyzed and designed according to the characteristics of FLGPSAR. The ideal of modularization is used in this simulation system, so it is flexible and effective to realize the simulation system. After applying the simulation system in the Matlab/Simulink (MS), the methods of choosing system parameters including pulse width and IF bandwidth are obtained. At the same time, the effect of the movement and incline of the platform, the harmonics levels, and the environment noise and so on is analyzed. And the radar system architecture is finally determined by system analyzing and simulation. By using this system architecture and the chosen parameters the radar system performance is optimized. This simulation system would be a foundation for effectively developing the FLGPSAR system.
