An Interferometric Synthetic Aperture Sonar Raw Signal Simulation Based on Points-Scatterer Model

Simulation of interferometric synthetic aperture sonar raw signal pairs is a very useful tool for mission planning and for testing of processing algorithms. An efficient Interferometric synthetic aperture sonar (InSAS) raw signal simulator based on pointer scatterer model has been recently presented. The simulator is founded on a two-scale composite acoustic model of a surface scattering and the surface is described by points. Due to the accurate and dense pointer scatterer model, the emulator is possible to simulate the decorrelation of InSAS well and truly. As an example, a series of reasonable simulation results are presented in this paper.
