摘要
研究了X波段雷达数据反演算法,为了验证反演算法的准确性,利用Longuet-Higgins海浪模型,通过选用适当的海浪谱和方向函数,仿真了三维随机海浪数据,利用反演模型得到的数据和仿真的海浪数据进行拟合,结果表明反演算法能够有效地实现海浪相关信息的提取;为了进一步检验算法的实用性,将反演算法得到的参数和实际的波浪浮标数据进行了对比,结果表明反演算法有一定的可行性。
An inversion algorithm of X Band Radar was studied in this paper. In order to validate its accuracy, the three-dimension sea waves were simulated by selecting appropriate sea spectrum and direction function trough Longuet-Higgins model. The numerical simulation of the sea waves and the X-band radar sea clutter have been done. The feasibility and effectiveness of the given model and algorithm have also been tested. Furthermore, inver- sion parameters and actual buoyed data were compared.
