一.问题的提出用一般微波雷达进行低角目标检测和跟踪已有不少文章进行过分析,但至今没有提出一种有效的方法。这是由于微波雷达天线波束一般较宽,同时由于地面或海面的不规则性在微波波段具有镜面性质,致使低角目标的检测和跟踪始终是一个难题.本文试图分析一下用毫米波雷达改进海上目标(海面或掠海飞行目标)的低角跟踪性能问题.本文所讨论的是天线高度(hr)高于目标高度(ht)时的情况,此时天线波束始终处于俯
I. Problems raised There has been a lot of articles on low-angle target detection and tracking using general microwave radar, but so far no effective method has been proposed. This is because the microwave radar antenna beam generally wide, at the same time due to the irregularity of the ground or sea in the microwave band mirror properties, resulting in low-angle target detection and tracking is always a problem.This paper attempts to analyze the use of millimeter wave radar to improve the sea The low-angle tracking performance of the target (sea or sea-swept target) is discussed in this article when the antenna height (hr) is above the target height (ht)
