Abstract
Abstract: In order to meet the application requirements of synthetic aperture radar (SAR) in ocean remote sensing, a fast simulation method for the ship target SAR echo generation is presented, which carries out the accurate electromagnetic modeling to the important ship targets. “Four paths" model is used to calculate the complex echo between the ship target and sea surface, and the facet model is used to model the sea surface backscattering. After the two parts of echoes being synthesized, the SAR echo of whole scene is gotten, and the echo is processed by spot SAR imaging processing algorithm to verify the effectiveness. The proposed fast method, avoids the complex electromagnetic simulation on the whole imaging area, effectively improves the electromagnetic calculation efficiency on big scene. By applying the high frequency electromagnetic algorithm in the target area, the electromagnetic scattering property of the ship target is retained, which provides an accurate and efficient simulation algorithm for the SAR echo simulation.
