SYSTEM AND METHOD FOR USING A MULTIPLE INPUT MULTIPLE OUTPUT SYNTHETIC APERTURE RADAR FOR A WIDE BAND HIGH RESOLUTION IMAGE CAPABLE OF IMPROVING AN AZIMUTH DIRECTION RESOLUTION

摘要

PURPOSE: A system and method for using a multiple input multiple output synthetic aperture radar for a wide band high resolution image are provided to widen an observation width by decreasing a repeated pulse frequency.;CONSTITUTION: An antenna unit(100) includes a plurality of antennas in which different channels are allocated. A first signal processor(200) modulates a linear frequency through a distance direction compression process. The linearly frequency-modulated signal is continuously transmitted to an observation area. A second signal processor(300) successively performs a phase compensation process, an RCMC(Range Cell Migration Correction) process, an interleaving process, and an azimuth direction compression process. An image processor(400) receives a signal from the second signal processor and outputs the received signal as a 2D image signal.;COPYRIGHT KIPO 2012
