THE TRANSFORMATION AND DETECTION OF ACOUSTIC ECHO SIGNALS WITH SWTTYPE SODAR PROBING SYSTEM
<正> The Acoustic Sodar is widely used in the probe of the atmospheric boundary layer. We will use the Phase Locked Tracking Filter (PLTF) as the total program to measure the Doppler frequency deviation signal f_d of random weak signal under the condition of an interference of strong noise and also we will use the transformation method of V-F-BCD
