合成孔径雷达目标特征提取新方法
Novel feature extraction method for synthetic aperture radar targets
摘要
Abstract
In order to extract geometric and electromagnetic features of targets from the radar echo,a novel parameter estimation algorithm for attributed scattering center decomposition and extraction is presented,which is steady and fast.By simplifying the model with consideration of real synthetic aperture radar working conditions,a simplified model is deduced.It is used to construct the base to represent the radar echo.The RELAX algorithm is utilized to determine the model parameter in an iterative way,with fast Fourier transform used for acceleration.Moreover,the maximum searching intervals and ranges are deduced in literature.Both simulated data and real measured data illustrate that our method is not only precise but also robust.Moreover,through the comparison with traditional methods,the efficiency has been improved effectively.关键词
