| 摘 要： | 分析了影响雷达海杂波反演海洋蒸发波导的几个关键因素，建立了蒸发波导修正折射率剖面的两参数模型，提出了一种提高蒸发波导反演精度的方法。由于天线高度不同时，雷达接收的海杂波携带的波导特征信息不同，基于天线伺服系统，建立了可调天线高度雷达系统的两参数蒸发波导反演模型。通过与固定天线高度的蒸发波导两参数反演比较，验证了该反演模型具有较高的稳定性和反演精度。

| Abstract: | The key factors affecting ocean evaporation duct inversion from radar sea clutter are analyzed,and a dual-parameter modified refractivity profile for evaporation duct is modeled.A method for improving the inversion precision is introduced.Because the sea clutters from different antenna heights carry different duct information,the improved inversion model for evaporation duct is constructed using radar clutters from changeable antenna heights,with the antenna servo system employed.Through duct inversion comparisons with the case of fixed antenna height,the high inversion stability and precision of this model are confirmed. |
