Study on Target Detection Method by Coherent Integration for Frequency Modulation Coded Radar Systems

Abstract

在现代战场上,高速低可侦测性目标以及各种电子干扰手段的出现对雷达的目标探测性能提出了更高的要求。调频编码雷达作为一种新型的高距离分辨率雷达,具有数据利用率高、对雷达瞬时带宽要求不高以及抗干扰性能强的优点。为了增强调频编码雷达对微弱目标的检测能力,进一步研究调频编码雷达的相干积累检测方法具有重要意义。因此,本文主要开展了如下创新工作: (1)针对调频编码雷达,提出了一种基于运动补偿的相干积累检测方法。首先对调频编码雷达的回波信号进行建模,利用最大似然估计(maximumlikelihoodestimation,MLE)对目标的运动参数进行精确估计,同时构造运动参数的似然函数作为分析工具。接着根...In the modern battlefield, with the technology development of electronic jamming and the appearance of high-speed, low-observable targets, the demands for better radar detection performance become more pressing. As a new kind of high range resolution radar, frequency modulation coded radar has advantages such as high data utilization, low instantaneous bandwidth and strong anti-jamming capability....学位:工程硕士院系专业:信息科学与技术学院_工程硕士(电子与通信工程)学号:2332013115326
