摘要
雷达目标识别是现代雷达技术的一个十分重要的发展方向。由于高分辨雷达一维距离像(HRRP)能够提供更加精细的目标结构和形状信息,因此,基于一维距离像的雷达目标识别研究具有重要的理论意义和现实意义。本文主要研究基于线性调频信号的高分辨力一维距离像的实现,采用匹配滤波方法,利用回波信号的复包络进行分析,通过对点目标的仿真成像,很好地得到一维高分辨距离像,对雷达目标识别技术有广泛的应用价值。
Radar target identification is an important developing field of modern radar technology. Since HRRP（High- Resolution Range Profile）can provide more accurate target structure and shape information, research on radar target identification based on Range Profile is of significance for both theory and practice. This paper introduces the realization method of HRRP based on LFM signal. The HRRP is obtained by analysising echo signal and simulating image, using matched filtering method. It will be of great value to radar target identification.
