%X In process of observing ocean wave with nautical radar,the roughness of offing will be changed for emergence of rainfall.So the intensity of echo signal which received from radar will be influenced.In this paper an analyzing and processing method is proposed for rainfall observation data in wave monitoring system by nautical radar.Firstly the statistic characteristic- mean value and variation coefficient of radar echo image are used as classifying criterion to distinguish rainfall and non-rainfall.Then the median filtering algorithm is approached to dealing with rainfall observation data in order to reduce the influence from rainfall.The experimental results indicate that the algorithm proposed in this paper has a good robustness and general performance.
