Key Challenges in True Multistatic OTH Radar Concepts based on HF-Radar in iFURTHER
2024 International Radar Conference (RADAR)The system concept of a multistatic network of collaborative high frequency (HF) over-the-horizon (OTH) radar nodes has been proposed and is being tested in the European Union-funded study iFURTHER.

OTH radar phenomenology: signal interpretation and target characterization at HF
IEEE Aerospace and Electronic Systems Magazine, 2017Implicitly or explicitly, the extraction of information from radar echoes is based on a physical model of the interaction between the radar system and the target, the study of which is sometimes referred to as radar phenomenology [1]. It follows that the detail and fidelity of the physical model determine the prospective observables, the accuracy of ...

HF-OTH Skywave Radar for Missile Detection
, 2008 In this paper missile detection capabilities of an HF-OTH skywave will be analysed and assessed. Specifically we focus on a challenging scenarios that is the detection of ballistic missiles in their boost phase for early activation of defence systems. Missile Radar Cross Section (RCS) is calculated during target flight taking into account of frequency ...

Orthogonal waveform support in MIMO HF OTH radars
2007 International Waveform Diversity and Design Conference, 2007HF skywave radar performance and flexibility can benefit from transmission of multiple orthogonal waveforms in a multiple-input, multiple-output (MIMO) radar architecture. Several practical limitations need to be considered in such a design. One issue is that many HF radar transmit arrays are over-sampled spatially to allow for operation over a ...

HF-OTH Skywave Radar: A Method for Peak Power Evaluation
2006 International Radar Symposium, 2006This paper addresses the problem of peak power evaluation in HF OTH skywave radar. A wide number of factors affect the performance of such systems, specifically ionospheric propagation and absorption losses, as well as external radio noise interferences.

Ship target detection for HF groundwave shipborne OTH radar
IEE Proceedings - Radar, Sonar and Navigation, 1999The spreading of the first order Bragg lines that result from movement of the radar platform will obscure targets with Doppler frequencies within the range of this spreading. This is the main difficulty for HF groundwave OTH radar in detecting ship targets in a shipboard environment. In the paper, the properties of the spread spectrum are analysed with

Modeling and performance of HF/OTH radar target classification systems
IEEE Transactions on Aerospace and Electronic Systems, 1992The effects of a class of multipath propagation channels on the performance of a over-the-horizon (OTH) radar target classification system are considered. A Rician frequency-selective fading channel model is employed to characterize the effects of the multipath propagation medium and evaluate the performance of radar target classification systems.

Fetch limited sea scattering spectral model for HF-OTH skywave radar
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Sea Normalized RCS, and Doppler spectra have been revised for HF-OTH Clutter Modelling. The Hasselmann model is firstly introduced to predict the sea directional spectrum of fetch-limited sea and results have been compared with the Pierson-Moskovitz model used for large scale ocean remote sensing.

A Simulation Framework for HF-OTH Skywave Radars: the Received Signal
, 2007 This paper is focused on the analysis and the simulation of a model for the received signal of a HF-OTH skywave radar. More precisely, this work aims to identify and model the main components of a HF-OTH skywave radar received signal, in order to ...
