Research on Detection of Rainfall Noise Based on Marine X-Band Radar

In order to effectively detect the rainfall noise in the marine X-band radar data, an algorithm is proposed based on the high intensity and high density characteristics of rainfall noise. By means of the algorithm, the preliminary detection is firstly realized by binarization processing and texture feature analysising, then using region growing algorithm to reprocess the preliminary detection, the rainfall noise detective is realized finally. The results show the algorithm is effective and practical in the rainfall noise detection.
