Vehicle control classification and identification through ISAR imaging

The great advantages arisen in millimeter-wave frequencies have made possible the development of high range resolution radars. The capability of using high bandwidths (Gigahertzs) increases the range resolution allowing the obtaining of target´s radar signatures. Through these signatures some patterns of the targets can be extracted like its size, velocity or maybe some specific features which facilitates its recognition, classification and even identification. The increase in azimuth dimension obtained, like it is explained in this paper, thanks to Doppler processing, allows to get better estimations of the targets characteristics
