| 摘 要： | 设计同时探测海面舰船目标和海上高速飞行目标的高频地波雷达信号体制是高频地波雷达实现海空兼容探测的关键。本文分析了高扫频重复频率的确定截断ＦＭＣＷ信号在去斜率方式下处理高速运动目标时产生较高的距离旁瓣的主要原因。针对这一问题首次提出了地波超视距雷达探测海上高速运动目标的ＨＳＲＦＦＭＩＣＷ信号的相关运算处理方法。仿真结果证明了这种方法的有效性。本研究为进一步完善地波超视距雷达探测的功能提供了新的方法。

| Abstract: | Designing a signal form which is compatible both for ship and air target detection is the key to the HF (high frequency ) radar which works in a ship plane mode. This paper analyzes the reason why the FMCW signal determined with high sweep repetition frequency (HSRF) generates high range sidelobes in deramping processing.In order to solve this problem,a correlation method of HSRF FMICW signal is presented for rapid moving target processing. Simulation results show that this method is effective.This research makes progress in HF radar area. |
