Abstract

Abstract:

The direct SAR imaging method has a low efficiency when used for realizing the target echo simulation and SAR imaging,which will meet,with difficulty,the requirement of rapid SAR generation in the closed-loop verification process of sea detection guidance.In this paper,we propose a SAR simulation method based on three-dimensional(3D) scatter centers.First of all,the 3D scattering centers of a ship target from different perspectives are obtained by the 3D fast imaging based on the ray tube integral and 3D scattering center extraction based on the CLEAN algorithm.Then,the target SAR echo data and image aggregation processing are quickly calculated to obtain the SAR complex image through the geometric modeling of SAR imaging from the corresponding perspective.The method makes comprehensive use of electromagnetic scattering center extraction and complete SAR processing flow,which can significantly improve the efficiency and flexibility of target imaging simulation under the condition of maintaining the electromagnetic calculation accuracy.The calculation accuracy,efficiency,and flexibility of the proposed method are verified by taking a typical ship target as an example.

Key words: synthetic aperture radar imaging simulation, 3D scattering centers, ship targets
