To overcome the contradiction between wide swath and high azimuth resolution in synthetic aperture radar system, matrix inversion method is investigated to unambiguously recover the nonuniformly sampled azimuth signal. In this paper, to achieve the reconstruction filters, the system matrix is decomposed into a Vandermonde matrix and a diagonal matrix. An explicit expression of the reconstruction filters...
This paper presents a fast algorithm for imaging based on Ultra-wideband (UWB) impulse radar. An Impulse Radar system was designed to image the objects which were placed on the motion rail based on the radar sensor. The image could be clear but the speed would be too slow by using time-domain back projection algorithm. This algorithm the paper presents, which can make a quick imaging, also ensures...
