摘　　要：在海洋降雨环境中,弹载雷达的探测距离受降雨衰减的影响较为明显,对海上作战产生较大影响。由于降雨的空间均匀性较差,精确计算降雨衰减对弹载雷达探测距离的影响难度较大。针对此问题,基于国际电信联盟无线电通信部门(International Telecommunication Union Radio communication sector,ITU-R)提供的降雨衰减预测模型,提出了一种多点路径雨衰作用下的雷达探测距离计算方法,分析了影响雷达探测距离的主要因素并提出了改进建议;结合作战平台空间分布特点,计算了某海域降雨环境对典型频段主动雷达探测距离的影响,对导弹的作战使用具有一定的参考价值。In the marine rainfall environment,the range of missile borne radar is significantly affected by rainfall attenuation,which has a great impact on the naval operation.Due to the poor spatial uniformity in rainfall,it is difficult to accurately calculate rainfall induced attenuation over radar detection range.Aiming at this problem,a calculation method of radar detection range under multi-path rainfall attention is proposed based on the ITU-R rainfall attenuation prediction model.Also,the main factors affecting the radar detection range are analyzed and the suggestions for improvement are proposed.Combined with the spatial distribution characteristics of the combat platform,the influence of rainfall environment on the active radar detection range in the typical frequency band of the sea is calculated,which has a certain reference value for the missile combat operation.
