Diffraction From Metallic Objects in Radar Imaging—Theory, Simulation, and Experimental Verification

IEEE Journal of Microwaves, 2022
The paper describes the modelling of diffraction effects in radar imaging scans at and near sharp-edged metallic objects as the aperture dimension is close to the dimension of the object to be scanned.

Dealing with co‐channel interference in multi‐channel airborne passive radar

IET Radar, Sonar & Navigation, 2021
We address the problem of co‐channel interference (CCI) in multi‐channel airborne passive radars using digital broadcast signals of opportunity. A framework for suppressing the CCI is proposed, based on a two‐stage approach, which reflects the range ...

Statistical Analysis of Bistatic Radar Ground Clutter for Different German Rural Environments

Sensors, 2020
This article presents the statistical analysis of bistatic radar rural ground clutter for different terrain types under low grazing angles. Compared to most state-of-the-art analysis, we present country-specific clutter analysis for subgroups of rural ...

Evaluation of turbulent dissipation rate retrievals from Doppler Cloud Radar [PDF]

, 2012
Turbulent dissipation rate retrievals from cloud radar Doppler velocity measurements are evaluated using independent, in situ observations in Arctic stratocumulus clouds. In situ validation data sets of dissipation rate are derived using sonic anemometer

Sampling criteria for mutual over‐the‐air synchronisation of radar sensors

Electronics Letters, 2021
Synchronisation of radar systems can be used to suppress interference and enable communication between radars. In this paper, a generalised Kuramoto model is proposed, which can be used to synchronise pulse repetition frequencies of two radars over‐the ...

High-frequency radar-derived coastal upwelling index

State of the Planet, 2023
Abstract. Coastal upwelling has been extensively studied since it plays a critical role in the connectivity between offshore waters and coastal ecosystems, which has impacts on water quality, fisheries, and aquaculture production. Significant efforts have been devoted to the quantification of the intensity, duration, and variability of this phenomenon ...
