Title: Study of target identification using electromagnetic poles

Abstract

Three techniques for identifying radar targets by using their electromagnetic resonances or poles are studied. A singular advantage of such a pole-based approach is that it can operate independently of the target excitation. A library of pole sets is used both to generate the target waveforms (to which noise is added) and to correlate with parameters extracted from those waveforms. The techniques studied are linear prediction, residue calculation, and pole calculation. Direct waveform correlation was also evaluated for comparison with the pole-based techniques. Using 10-run-average correlation values, error-free identification was accomplished by pole calculation at a peak-signal-to-peak-noise ratio as low as 10, and by waveform correlation at a noise ratio of unity.
