摘要
本文结合合成孔径雷达二维断面成像中平面波展开法与二维B-P算法,设计了一种新的柱面场三维RCS成像算法。此算法将成像步骤分为相位补偿二维纵向断面成像以及B-P算法水平面成像,用于柱面场RCS成像系统中在测试过程中可实时监控二维纵向断面成像效果。经仿真数据与实测数据验证,此成像算法成像效果良好,成像分辨率与理论相符,可应用于工程应用中。
A novel three-dimensional(3-D) microwave image reconstruction algorithm based on cylindrical Near-Field measurements is presented. This algorithm combines 2-D plane wave spectrum(PWS) expansion method which and 2-D back-projected(B-P) method together to achieve 3-D image of target. With this method, 2-D real-time image could be seen during the measuring period. The imaging results from simulation and experiment prove correctness of the algorithm. With a high resolution, this algorithm could be used on real measurement system.
