A method of featur e ex t ract ion of incoherent averag e, mult iresolut io n decompo sit io n, Fourier t ransformat ion is pro posed. The hidden Markov model ( HMM ) technique is used to ident ify featur e sequences result ing f rom r ange prof ile sequences. A data set of r eal radar rang e prof ile of three class air craf ts got ten from an ISAR is used to test the ef fectiv eness of above methods. Ident ification accuracy of 99. 33 % is obtained.
