船舶在海面航行时，雷达发射信号易受到海雾等自然条件的影响，导致雷达信号接收器采集的回波信号中存在大量噪声，当雷达信号接收器的灵敏度相对较低时，船舶雷达系统目标探测的精度较低。针对这一问题，行业内采用多种先进技术对船舶雷达信号接收系统进行灵敏度的提升。本文对现有的雷达接收系统的关键硬件模块进行详细分析，基于PLC技术开发了一种具有高精度的船舶雷达信号接收系统。
When the ship is sailing on the sea, the radar transmission signal is easy to be affected by natural conditions such as sea fog, resulting in a large amount of noise in the echo signal collected by the radar signal receiver. When the sensitivity of the radar signal receiver is relatively low, the target detection accuracy of the ship radar system is low. To solve this problem, the industry has adopted a variety of advanced technologies to improve the sensitivity of ship radar signal receiving system. This paper studies a ship radar signal receiver based on PLC technology. Firstly, the key hardware modules of the existing radar receiving system are analyzed in detail. Then, based on PLC technology, a ship radar signal receiving system with high precision is developed.
