摘要
导航雷达系统是整个船舶交通网络的重要组成部分,在目标跟踪﹑防碰撞系统等方面有较为广泛的应用。雷达信号不仅受到海上各类环境噪声干扰,同时其频率源的载波频率波动也影响整个导航雷达系统定位精度,对船用导航雷达信号的测试与分析尤为重要。本文设计一种基于混频技术的雷达信号源测试系统,并对测试结果进行了分析。
The navigation radar system is an important part of the whole ship traffic network. It is widely used in target tracking and anti-collision system. In the radar signal receiving, not only is it disturbed by various kinds of environmental noise at sea, but also the carrier frequency of its frequency source affects the positioning accuracy of the whole navigation radar system. It is particularly important to test and analyze the signal of marine navigation radar. In this paper, a radar signal source test system based on mixing technology is designed. Finally, the test results are analyzed.
