A method of recognizing a radar target comprises producing a sequence of Doppler spectra of radar returns form a scene and producing therefrom a sequence of Doppler feature vectors for a target in the scene. Hidden Markov modelling (HMM) is then used to identify the sequence of Doppler feature vectors...http://www.google.es/patents/US6801155?utm_source=gb-gplus-sharePatente US6801155 - Method and apparatus for recognising a radar target
