Multi‐Shot Estimation of Resonance Parameters of Late‐Time Radar Returns in Clutter
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.A technique for estimating the resonant features of radar targets based on their late‐time returns (LTRs) is presented. Experimental results demonstrate that the technique is effective in scenarios where the target is embedded in significant clutter, and the signal‐to‐noise ratio in the LTRs is quite low.

IET Science, Measurement &Technology, Volume 19, Issue 1, January/December 2025.This study demonstrates that the conventional 8% physical volume rule for Equipment Under Tests (EUTs) in reverberation chambers is an unreliable guideline for maintaining field uniformity. Our full‐wave simulation results prove that an EUT's electrical size and geometric shape are the more critical factors.
