Synthetic Aperture Radar Signal Simulation

The problem for simulation of SAR raw signal and the terrain-echo simulation are discussed .The principle of high resolution imaging is analysed. The expressions of imaging models and the method of imaging are gained. The problem of the time domain walk compensation and picture mistiness are discussed. How to build imaging parameter is narrated. The character of SAR picture is analysed and R-D or Chirp-Scaling algorithm is introduced. The simulation of point, point array, two-dimensional object, three-dimensional object have been finished. At the end of this paper a hardware simulator of SAR raw signal is introduced .The system of radar equipment, the system of signal disposal and the system of raw echo signal simulation are analysed.
