Abstract: The back-scattered echo signals recorded in an acoustic radar system provide information on the characteristic patterns of atmospheric boundary layer (ABL) within a height of 1 km from the ground. These acoustic imageries are composed of range and intensity information and usually contaminated with varieties of noises. An algorithm based on image processing technique was developed to remove most of the noises and a method of global thresholding for extraction of patterns from the echograms has been discussed.
