海杂波后向散射系数经验模型研究
Empirical model research on backscatter coefficient of sea clutter
摘要
Abstract
In order to improve the detection performance of radar working in the marine environment,GIT,TSC,NRL three empirical models of typical backscatter coefficient were simulated based on the backscattering properties of the sea clutter. The results were compared with the measured data. MSD is adopted as the evaluation criteria of fitting goodness to analyze the fitting characteristics of the three models. The applicability of the three models is given. The analysis results show that the im-proved NRL model fits with the measured data best,the TSC model is better,and the GIT model is worst,whose applicability presents different characteristics with the change of sea state,grazing angle,polarization mode.关键词
