Abstract :
A new millimeter-wave (MMW) radar target classification approach has been proposed using polarimetric information to obtain stable amplitudes of range profiles, and neural learning to extract angle invariant features of range profiles. The means of the polarimetric processing for reducing the speckle can enhance ability to discriminate targets. Compared with conventional approaches, the subclass features obtained carry more information due to the neural learning and thus make the correctness of target classification higher. The simulation results have verified the validity of this approach
