Research on the technology of monopulse SAR ground moving target indication

Synthetic aperture radar (SAR) is a sort of high resolution imaging radar but the image of moving objects are often smeared and displaced in azimuth. In this paper, ground moving target indication (GMTI) with a monopulse SAR is introduced. The present method makes it possible to indicate the moving target in imaging scene and correct the azimuth displacement with the focused data from the sum and difference monopulse channels.
