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 ...

Multistatic micro-Doppler radar signatures of personnel targets
This study extends the theory of the micro-Doppler effect into the multistatic domain, and considers how the multistatic micro-Doppler signature (μ-DS) will affect radar automatic target recognition (ATR).

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

Acoustic Integration of Detection and Communication for Air‐Sea Cross‐Domain Integrated Buoy Systems
Buoy systems suffer from significant positioning errors and the functional separation of detection and communication in complex underwater environments. This paper proposes a T/R3‐MPA‐based multibase positioning optimisation method to mitigate outlier interference, alongside an integrated detection‐communication buoy prototype.
