The method mainly uses multiple time-domain signals for each target and they are processed to give feature vectors in frequency domain. These vectors contain target-specific information related with characteristics (dimensions of substructures material properties etc.) of the known targets. The target recognition is employed by using test (unknown) target's scattering signal. This time-domain signal is processed in an inverse way to get a frequency-domain test vector. Then the characteristics of test target are assigned as these of one of the known targets with a basic template-matching approach between test vector and feature vectors of these targets. The method is demonstrated for three realistic small-scale airplane. For an ultrawideband system of 0.7-18 GHz more than 85 percent accuracy has been obtained even under moderate signal-to-noise (SNR) ratio of about 10 dB.Englishultrawideband, inverse scattering, radar signal processing, resonance regionIDENTIFICATIONConference Object
