UNDERGROUND TARGET DETECTION SYSTEM AND METHOD FOR TARGET SIGNATURE ENHANCEMENT

摘要

The present invention relates to a system and a method to detect an underground target to intensify a target signal. According to the present invention, the method to detect an underground target comprises the steps of: measuring radar signals on each position by executing an operation of receiving radar signals radiated from a sending antenna in a receiving antenna; executing a short time Fourier transform to the radar signals measured on each position; obtaining a profile graph which represents a first peak value position extracted in correspondence to each position in a short time Fourier transform graph representing a result of the short time Fourier transform; and determining the position corresponding to the most extremely protruded part in the profile graph as the target position. According to the present invention, a system and a method to detect the underground target while highlighting the target signal is provided.
