THE DATA CORRECTION OF SEA CLUTTER IN THE WAVE MONITORING SYSTEM OF NAUTICAL RADAR

TANG Yan-hong,HAO Yan-ling,LU Zhi-zhong(College of Automation,Harbin Engineering University,Harbin 150001,China)  
For the purpose of accomplishing wave information inversion,precise correction of sea clutter data is necessary.In this paper,a correction algorithm is proposed for processing sea clutter data.First,for tackling geometric aberrance of radar imaging,a fast geometric correction method based on the separation of azimuth and range is proposed combined with the real working parameters.Then,for coping with radiation quantity aberrance of sea clutter data along with scanning beam,a nonlinear relative radiometric correction method along with scanning beam is put forward to deal with the data.An analysis of the correction results shows that,after correction,both the data processing speed and the image quality and precision achieve the engineering practice requirement of wave analysis.
