线性频率分集阵列SAR增强后向投影算法
Linear frequency diversity array synthetic aperture radar imaging based on enhanced back-projection algorithm
摘要
Abstract
Based on the signal model of multiple carrier frequency (MCF) for linear frequency diversity array synthetic aperture radar (LFDA-SAR),we propose an enhanced back-projection (EBP) algorithm.Compensation for the quadratic phase error in echoes is executed and the spatial-variant range drifting amount and phase of the target are amended during the process of back-projection.The proposed algorithm can effectively rectify the image blurring and geometric distortion problem in classical back-projection imaging results,realize a high precision imaging of targets with an arbitrary imaging geometry and distinguish adjacent strong and weak targets.All results verify the effectiveness of the proposed algorithm.关键词
