Multi‐Shot Estimation of Resonance Parameters of Late‐Time Radar Returns in Clutter

ABSTRACT The resonance parameters of late‐time returns (LTRs) can be used as features in the identification of radar targets. However, reliable estimation of the complex frequency of each resonance is notoriously difficult. This is a result of the short duration of the LTR, its low effective signal‐to‐noise ratio (SNR) and the inherent sensitivity of the estimation problem. These issues are exacerbated when the radar background includes …
