APPLICATION OF MEM SPECTRAL ESTIMATION TO MU RADAR OBSERVATION

Preliminary results of the wind velocity estimation using the Maximum Entropy Method (MEM) to MU radar observation data sets are presented.The comparison of the results from the periodogram method and the MEM shows that the MEM estimation is reliable,and has higher accuracy,resolution and detectability than the estimation from periodogram method.The high accuracy power spectrum obtained by the MEM is very useful to studying the atmospheric turbulence structure.However.the MEM needs the longer computing time for obtaining the high accuracy spectrum.Particularly,the estimation of MEM will bring serious deviation at lower signal-to-noise ratio.
