An anti‐jamming method in multistatic radar system based on convolutional neural network
IET Signal Processing, 2022 For the existing jamming discrimination methods on the multistatic radar system, the single feature of target echo space correlation is utilised as the metric, which leads to the lack of comprehensive feature extraction and universal discrimination ...

The Case for Combining a Large Low-Band Very High Frequency Transmitter With Multiple Receiving Arrays for Geospace Research: A Geospace Radar [PDF]
, 2019 We argue that combining a high‐power, large‐aperture radar transmitter with several large‐aperture receiving arrays to make a geospace radar—a radar capable of probing near‐Earth space from the upper troposphere through to the solar corona—would ...

Cooperative Radar and Communications Signaling: The Estimation and Information Theory Odd Couple [PDF]
, 2014 We investigate cooperative radar and communications signaling. While each system typically considers the other system a source of interference, by considering the radar and communications operations to be a single joint system, the performance of both ...

Modelling real‐world effects in near‐field SAR collections for compressive sensing
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.
