APPARATUS AND A METHOD FOR ENHANCING THE RESOLUTION OF A RADAR IMAGE DATA BASED ON WIDEBAND LINEAR FREQUENCY MODULATION WAVEFORM, USING A SIGNAL PROCESSING METHOD

摘要

PURPOSE: An apparatus and a method for enhancing the resolution of a radar image data based on wideband linear frequency modulation waveform are provided to improve the resolution of the radar image data which is obtained through radar.;CONSTITUTION: A transmitting and receiving unit(102) transmits a signal to a target and receives a reflected signal from the target. A matching filter(104) implements the Fourier transformation of the received signal. The transmitted signal is matched using the transformed signal and the target in order to implement inversed Fourier transformation. An extractor(106) extracts distance information with respect to the target based on the image data of the inversed Fourier transformed signal. The resolution of a cell is obtained using the extracted distance information. The region of the target is extracted. A measuring unit(108) measures image data with respect to a target in the extracted target region.;COPYRIGHT KIPO 2011
