Joint integrated track splitting for multi-path multi-target tracking using OTHR detections

EURASIP Journal on Advances in Signal Processing, 2018
In target tracking applications where an over-the-horizon radar (OTHR) is used to gather measurements, one target may generate more than one measurement at each scan due to the multi-path propagation effect.

Societal Applications of HF Skywave Radar

Remote Sensing, 2022
After exploratory research in the 1950s, HF skywave ‘over-the-horizon’ radars (OTHR) were developed as operating systems in the 1960s for defence missions, notably the long-range detection of ballistic missiles, aircraft, and ships.

Real-Time Frequency Management System (FMS) for Sky-Wave High-Latitude Over-the-Horizon Radar (OTHR)

, 2022
A real-time frequency management system (FMS) is necessary for efficient operation of over-the-horizon-radar (OTHR) in high-latitude locations such as Canada's Arctic regions.

High-Resolution Doppler and Azimuth Estimation and Target Detection in HFSWR: Experimental Study

Sensors, 2022
In this paper, we present a new high-resolution algorithm for primary signal processing in High Frequency Surface Wave Radar (HFSWR). The algorithm has been developed to achieve and improve primary signal processing performance in existing HFSWR radars ...

Introduction to Coastal HF Maritime Surveillance Radars

Polish Maritime Research, 2019
This paper presents the main technical characteristics and working performances of coastal maritime surveillance radars, such as low-power High-Frequency Surface Wave Radars (HFSWR) and Over the Horizon Radars (OTHR). These radars have demonstrated to be

A Cognitive Beamforming Method via Range-Doppler Map Features for Skywave Radar

Remote Sensing, 2022
For skywave over-the-horizon radar, beamforming techniques are often used to suppress airspace radio frequency interference because the high-frequency band is shared by many devices.

A CFAR Detector Based on a Robust Combined Method With Spatial Information and Sparsity Regularization in Non-Homogeneous Weibull Clutter

IEEE Access, 2018
In over-the-horizon radar (OTHR), atmospheric noise and sea clutter exist in different regions of Range-Doppler map. To improve the detection performance, a combined method is proposed to identify the cell-under-test (CUT) and estimate the parameters of ...
