Paper Abstract

In the paper, we first present a general electromagnetic scattering model on the Doppler modulated features, i.e. the secondary modulation defined in the paper, resulting from the rotor rotation, propeller blades rotation and JEM. In addition, the airframe backscattering is given by dynamic facets modeling method for simulating the radar Doppler echoes. The processing of the measuring data shows the validity of the simulated radar echoes with the secondary modulation. A modified autocorrelation function is defined and used as the preliminary feature extraction of the secondary modulation, which is corresponding to the spectral analysis in frequency domain. Moreover, wavelet packets analysis performs the further feature extraction. Compared with 1D time domain feature extraction, 2D feature plane of wavelet packets decomposition show the higher correct recognition probability with the real-time classifier of fuzzy pattern comparator.
