L波段海水介电模型构建与误差分析
Construction and Error Analysis of L-band Seawater Dielectric Model
摘要
Abstract
Based on laboratory measurement data,a L-band seawater dielectric model in the form of salinity and temperature polynomials is constructed,and the coefficient of the model is solved by least square method and singular value decomposition technique.The new model is compared with the currently widely used Klein-Swift(KS)model,Meissner-Wentz(MW)model,and George Washington University(GWU)model.The results show that the RMSE errors between the new model values and the measured data are 0.09(real part)and 0.25(imaginary part),which are better than KS,MW and GWU models.关键词
