Uncoupled Digital Radars Creating a Coherent Sensor Network
Radar networks offer the possibility to overcome the limitations of single sensors. However, without coherent signal processing, the full potential of radar networks cannot be exploited.

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 and Multiple Frequency Imaging Resolution Analysis-Application to GPS-Based Multistatic Radar [PDF]
This paper focuses on the computation of the generalized ambiguity function (GAF) of a multiple antennas multiple frequencies radar system (MAMF). This study provides some insights into the definition of resolution parameters of a MAMF radar system. It turns out that the range and azimuth resolutions are not the most suitable criteria to specify the ...

Digital Beamforming and Non-Uniform Displaced Phase Centre Sampling in Bi- and Multistatic SAR [PDF]
The displaced phase centre (DPC) technique will enable a wide swath SAR with high azimuth resolution. In a classic DPC system, the PRF has to be chosen such that the SAR carrier moves just one half of its antenna length between subsequent radar pulses ...

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.
