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 ...

Multistatic search theory [PDF]
The characterizing feature of multistatic sensor systems is the inclusion of geographically independent receivers that might receive echoes from any source.

All-sky meteor radars have become a reliable and widely used tool for observing horizontal winds in the mesosphere and lower thermosphere (MLT) region. This provides vital data support for the study of dynamics in this region.

The linear sampling method (LSM) is a qualitative inverse scattering technique that can create good-fidelity imagery at low computational expense. However, it is challenging to use in many practical scenarios due to its need for wide-angle multistatic ...

Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Range‐Free Localisation for Monostatic Passive Radar Employing Multi‐Narrowband Illuminators
Range‐free localisation is considered for monostatic passive radar with multiple narrowband illuminators under unreliable time‐delay (range) measurements. Doppler/DOA (and optional Doppler‐rate) are fused in an ML framework, where velocity is iteratively updated to reduce the original 6‐D optimisation to a 3‐D position search.

Multistatic Radar Synchronisation Using COTS GPS Disciplined Oscillators [PDF]
The benefits of multistatic radar have been well understood for decades, though the challenges of implementing such systems have limited their development and subsequent operational use.

Characterisation and Classification of Resident Space Objects Using Radar Networks
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified

A Centralized Processing Framework for Foliage Penetration Human Tracking in Multistatic Radar [PDF]
A complete centralized processing framework is proposed for human tracking using multistatic radar in the foliage-penetration environment. The configuration of the multistatic radar system is described.
