DOA Estimation for HFSWR Target Based on PSO-ELM

IEEE Geoscience and Remote Sensing Letters, 2022
High-frequency surface wave radar (HFSWR) plays an important role in vessel target surveillance. However, HFSWR's inaccuracy of azimuth estimation caused by wide beams severely limits its detection ability. To solve this problem, a novel direction of arrival (DOA) estimation method based on extreme learning machine optimized by particle swarm ...

Performance analysis of target detection with compact HFSWR

2016 CIE International Conference on Radar (RADAR), 2016
High frequency surface wave radar (HFSWR) can continuously detect and track vessel targets over the horizon in real time. Compact HFSWR with a small aperture has the advantage of occupying smaller radar site, lower power consumption, easy deployment and maintenance.

Track retrodiction for HFSWR

2015 16th International Radar Symposium (IRS), 2015
In this paper, we explore the possibility of track retrodiction to improve the track performance. To make use of the extra multi-frame data, we borrow the Rauch-Tung-Striebel (RTS) algorithm for the track retrodiction purpose. Using a converted extended Kalman filter (CMEKF) as the baseline, its retrodicted version, namely the retrodicted CMEKF, shows ...

Ionospheric Interference Suppression in HFSWR

2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006
Over the past two decades, significant advances have been made in the use of high frequency surface wave radar (HFSWR) for remote sensing in an ocean environment. As one of the main outside interference, ionospheric interference may badly affect radar's performance.
