摘要
高频地波雷达探测距离主要受环境噪声和海杂波的制约。对于环境噪声占领优或海杂波占优的情况,已有相应的距离估算公式。但对环境噪声或海杂波可比拟的情况,使用上述公式所算得的结果误差较大,对雷达总体设计会产生一定影响。文中根据环境噪声和二阶海杂波的特性,从理论上推导了噪声与二阶海杂波共同作用下,通用高频地波超视距雷达探测距离估算公式,并在给定参数情况下计算了不同时段、不同海态下雷达对舰船目标的探测距离,从而为地波雷达总体设计提供依据。
The detection range of high frequency surface wave radar（HFSWR） is limited by environmental noise and sea clutters. There is a relevant estimation formula of detection range for environmental noise dominant or sea clutters dominant case. But for the situation of comparable environmental noise and sea clutters, it will lead to larger errors separately using the formulae and there would be certain impact on the overall design of radar. According to the characteristics of environmental noise and second-order sea clutters, this paper derived a unified estimation formula of detection range of HFSWR in the case that the detection rang is effeeted by environmental noise and sea clutters combined. Then for given parameters, the detection range of HFSWR for ship in different times of day and different sea states is calculated. It can provide basis for the overall design.
