Abstract :
Synthetic aperture radar raw data simulation serves many purposes such as testing different image formation algorithms, studying the interaction of electromagnetic waves with a scene being imaged, testing and validating different system design parameters, etc. Frequency domain raw data simulation can be used to generate the raw data efficiently, as compared to time domain simulation. However, contrary to the latter technique, the former cannot take into account motion errors. Recently, some techniques have been presented in the literature to simulate this case partially in the time and partially in the frequency domain, along with some approximations. In this paper, a simulation scheme based on the idea of partial time and frequency simulation is used, which improves computational efficiency and reduces certain approximations as compared to the already existing schemes.
