摘　　要：提出一种将射弹跳射线法和等效边缘电磁流法与线性调频信号雷达信号处理过程相结合的高频电磁散射算法,该算法能够快速准确计算复杂电大尺寸目标的大时宽带宽雷达回波信号。利用宽带雷达回波计算结果,获得了目标的一维距离像和二维ISAR成像,验证了方法的正确性。A fast novel method is presented, that combines SBR and EEC techniques with radar chirp signal processing. This fast method gives an order of magnitude speedup in computation time compared with conventional methods. With the wide radar signal data obtained by this method, range profiles and ISAR images are obtained, which validated the accuracy and efficiency of this fast method.
