An ISAR target motion estimation algorithm based on a differential semblance criterion
Electronics Letters, Volume 61, Issue 1, January/December 2025.This study presents a novel approach for improving rotational motion estimation in multistatic Inverse Synthetic Aperture Radar (ISAR) imaging through a Differential Semblance Optimization (DSO) criterion. By reducing discrepancies across images from multiple transmitter–receiver pairs, our method enables precise yaw rotation estimation and produces ...
