Multistatic Frequency and Polarimetry Adaptive Autofocus for Synthetic Aperture Radar Imaging of a Moving Target

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper presents a multistatic, frequency‐ and polarimetry‐adaptive autofocus algorithm (F‐Pol) for SAR imaging of moving targets undergoing complex, six‐degrees‐of‐freedom (6‐DoF) motion. Building on Localised Threshold Sharpness (LTS), the method exploits agreement across frequency sub‐bands and polarisation channels to improve pulse‐by‐pulse ...

Relativistic Effects in Bistatic SAR Processing and System Synchronization [PDF]

open access: yes, 2012
This paper addresses relativistic effects in bistatic and multistatic SAR systems and missions. It is shown that the use of different reference frames for bistatic SAR processing and bistatic radar synchronization is prone to nota-ble phase and time ...

Multi‐Angle Bistatic Scattering Characteristics of Ground Targets Observed by GB‐SAR Experiment

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper presents an experimental investigation of bistatic scattering characteristics using an outdoor ground‐based SAR system working in Ku‐band. Representative artificial and natural targets were measured and analysed to characterise their angular bistatic scattering responses and underlying scattering mechanisms.

Multiangle Bistatic SAR Imaging and Fusion Based on BeiDou-2 Navigation Satellite System

open access: yesLeida xuebao, 2015
Bistatic Synthetic Aperture Radar (BSAR) based on the Global Navigation Service System (GNSSBSAR) uses navigation satellites as radar transmitters, which are low in cost. However, GNSS-BSAR images have poor resolution and low Signal-to-Noise Ratios (SNR).

Joint Decoupling Optimization of Frequency Offsets and Array Elements for Frequency Diverse Arrays

open access: yesInternational Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
Frequency diverse array (FDA) has a distance‐angle–dependent beam direction map, which has a greater application advantage than phased array. However, due to the distance‐angle coupling and periodicity of its beam direction map, it makes the parameter information of the target obtained through FDA have ambiguous phenomena. Currently, researchers mostly

Bi- and Multistatic SAR: Potentials and Challenges [PDF]

open access: yes, 2004
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas which are mounted on separate platforms. Such a spatial separation has several operational advantages which will increase the capability, reliability ...
