雷达信号是VTS的子模块，也是VTS系统的核心构成部分，关系到船舶交通网络的可靠运行。雷达信号受海上环境噪声等因素的影响会产生载波频率波动，对导航雷达系统定位的精确性产生影响，所以有必要测试和分析雷达信号是否能够准确显示扫描信息。本文介绍了雷达工作原理，采用雷达信号模拟软件设计雷达信号测试程序，再搭建雷达信号测试模块和测试平台，最后对天线接口、网口、信号处理系统、海杂波抑制、目标识别进行测试和分析，表明雷达信号的可靠性。
Radar signal is a sub-module of VTS, and it is also the core component of VTS system, which is related to the reliable operation of ship traffic network. The radar signal is affected by the marine environment noise and other factors, and the carrier frequency will fluctuate, which will affect the positioning accuracy of the navigation radar system. Therefore, it is necessary to test and analyze whether the radar signal can accurately display the scanning information. This paper introduces the working principle of the radar, uses the radar signal simulation software to design the radar signal test program, builds the radar signal test module and test platform, and finally tests and tests the antenna interface, network port, signal processing system, sea clutter suppression, and target recognition. The analysis shows the reliability of the radar signal.
