加权平均法

Method of weighted mean
加权平均法
In the aspect of detection and high precision estimation of seafloor backscattering , algorithms of fast convergence of energy center and correlation of eigen - replica were developed . also studded were processing methods of weighted mean time ( wmt ) and bearing direction indicator ( bdi ) based on fft beam forming as well as high precision detection and estimation of time of arrival ( toa ) and direction of arrival ( doa ) using split beams phase difference detection technique
围绕海底反向散射信号的高精度检测和估计技术，开发了快速能量中心收敛算法和特征模型相关算法，研究了基于fft波束形成的加权时间平均与方位指示处理方法，并讨论了利用分离波束相位差检测技术的海底反向散射信号到达时间( toa )和到达方向( doa )的高精度检测与估计方法。
