Abstract

The research on new SAR algorithms are based on the theoretical background, algorithms verification using simulations and real-life data tests. The real experiments are expensive and time consuming. Due to that many researchers and software developers put many efforts to design and develop efficient tools for SAR simulations. Last years it has been design and developed many SAR simulators using different solvers [1], [3], [4], [5], [6], [7]. One of the simulator has been proposed and design by Warsaw University of Technology in 2003 [1], [3]. Due to the available that time computational power, the simulator was used to test a SAR algorithms based on the simple scene definitions, which include few dominant scattering in the scene [1], [3]. Such solution allowed for testing most of SAR algorithms, where have been tested such phenomena as non-linear flight path, geometrical distortion of the SAR image, etc [8], [9], [11], [12]. The computational power and required computer memory in the solver used for simulation depends linearly with the number of scattering points in the scene. That time it was not possible to simulate a complex and realistic scene including ground (consist of many scatterers) and shadowing, double and multi-bounds effect. The available in the market computational power and participation in the projects, where new SAR algorithms have to be developed [10], [11], [12], [13], [14], led authors to developed a new extended version of the SAR/ InSAR simulator. This paper presents new results of simulation, where the real DTM models of the Earth has been used.
