Over-the-horizon Radar Impulsive Interference Detection with Pseudo-MUSIC Algorithm

Over-The-Horizon Radar Tracking Using The Viterbi Algorithm

a new approach for coherent radar detection in pseudo- gaussian interference

in this paper a new algorithm is presented for coherent radar detection of targets, when distribution of the interference (clutter and noise) is non-gaussian. the neyman-pearson criterion is used for optimal detection and several successive received samples from a radar range cell are used for detection in the same cell. on the basis of recent empirical evidences, the interference distribution ...

Wideband signal design for over-the-horizon radar in cochannel interference

Ship detection in heavy sea clutter is a big challenge for over-the-horizon (OTH) radar. Wideband signal is helpful for improving range resolution and the signal-to-clutter ratio. In this paper, to support OTH radar employing wideband in cochannel interference, we propose environmental sensing-based waveform (ESBW) strategy, by considering transmit waveform design as an active approach and cogn...

MCMC data association algorithm applied to the French Over-The-Horizon Radar Nostradamus

Over-The-Horizon(OTH) Radars provide a survey of wide areas, using ionospheric reflections of the electromagnetic waves. Most of the time they have to face multipath problems: state estimation has to be done with measurements involving different observation models. To tackle this measurement-toobservation-model association problem, the Monte Carlo Data Association (MCDA) algorithm, and a deriva...

Over-the-Horizon Radar Multipath and Multisensor Track Fusion Algorithm Development

Over-the-horizon radar (OTHR) and microwave radar networks can together generate track data over a wide surveillance region. However the data is often subject to ambiguity and uncertainty due to the complexities of the HF signal propagation environment, which give rise to multipath OTHR tracks, as well as ambiguities in target associations between multiple microwave radars. This report describe...
