APPARATUS AND METHOD FOR DETERMINING OF TARGET USING RADAR

摘要

PURPOSE: A target decision device using radar and a method thereof are provided to accurately determine multiple targets. CONSTITUTION: A target decision device (100) using radar comprises a bit signal generator (110), a bit frequency extractor (120), and a determining unit (140). The bit signal generator produces a bit signal using a radar transmission signal and a radar reception signal for one or more targets. The bit frequency extractor extracts up-bit frequency and down-bit frequency from the produced bit signal. A power spectral density calculation unit calculates power spectrum density in every predetermined frequency cell sections for the extracted up-bit frequency and down-bit frequency. The determining unit determines whether the target is the same target or not using the similarity between power spectrum densities of the up-bit frequency and the down-bit frequency. A target position calculation unit calculates the position of the target in a frequency cell section in which the similarity between power spectrum densities of the up-bit frequency and the down-bit frequency is higher than a reference similarity value.
