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 ...

Multistatic Synthetic Aperture Radar Autofocus for Back Projection Imaging of a Moving Target
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper presents a new metric‐based autofocus approach, called Localised Threshold Sharpness (LTS), which employs Multistatic SAR data to localise and focus a target moving with up to six degrees of freedom motion on a real‐time, pulse‐by‐pulse basis.

General Processing Approach for Bistatic SAR Systems: Description and Performance Analysis [PDF]
, 2010 For its intrinsic properties, bistatic SAR processing cannot be approached in the same manner monostatic SAR process- ing is approached. In general, a bistatic SAR processor is more than a powerful focussing algorithm.

Ionospheric Faraday Rotation Angle Estimation for Bistatic Spaceborne SAR
Electronics Letters, Volume 61, Issue 1, January/December 2025.This paper proposes a Faraday rotation angle estimation method for bistatic spaceborne SAR. The effectiveness of the method is verified through simulation experiments and the performance of the method is analysed. Under different SNR and filtering window sizes, the estimation error range is 0.02°–0.26°. ABSTRACT Bistatic synthetic aperture radar (SAR)
