基于高频超视距雷达的船舶海上远距离目标探测技术是一种利用雷达系统进行海上目标探测和测距的技术。该技术利用高频电磁波的特性，通过发射电磁波并接收目标反射回来的信号，实现对远距离目标的探测和定位。该技术的关键在于如何实现雷达探测过程的海杂波、地杂波等干扰信号的过滤，提高远距离探测的高频超视距雷达系统的工作精度。本文分别从高频超视距雷达的工作原理、杂波干扰信号建模、信号过滤、远距离目标探测算法等方面进行研究，通过该目标搜索和定位技术，船舶可以在海上实现对远距离目标的实时监测和跟踪，提高海上安全性和航行效率。
The maritime long-distance target detection technology of ships based on high-frequency over-the-horizon radar is a technology that uses radar systems for sea target detection and ranging. This technology uses the characteristics of high-frequency electromagnetic waves to detect and locate long-distance targets by transmitting electromagnetic waves and receiving signals reflected back from targets. The key to this technology lies in how to filter interference signals such as sea clutter and ground clutter in the radar detection process, and improve the working accuracy of high-frequency over-the-horizon radar systems for long-distance detection. This paper studies the working principle of high-frequency over-the-horizon radar, clutter interference signal modeling, signal filtering, long-range target detection algorithm, etc., through this target search and positioning technology, ships can realize real-time monitoring and tracking of long-distance targets at sea, and improve maritime safety and navigation efficiency
