WebThe objective of this thesis is the Automatic Target Classification (ATC) based on radar backscattered Ultra WideBand (UWB) signals. The classification of the targets is realized by making comparison between the deduced target properties and the WebIn the Rayleigh approximation, only the lowest order contributions in are considered. This is equivalent to setting all a n and b n to zero except b 1, which reduces to b 1 = 2i 3 m2 1 …
