SAR simulation of realistic target using general purpose EM simulators

There have been so many research works on the SAR (Synthetic Aperture Radar) image generation using EM (Electro Magnetic) simulation. Particularly, there are several dedicated S/Ws for SAR image generation and analysis. But, most of them are not available to the public due to the reason for defense and security. In this paper, we describe the generation of SAR images for a realistic target model using the general purpose EM simulator like FEKO and demonstrate its validity by processing the simulated SAR raw data with range-Doppler algorithm. This method can benefit us many advantages like performance evaluation for target detection, estimation and target recognition with realistic target model in a cost-and-time effective way.
