Signal processing of sky wave over-the-horizon radar
IIEEE International Conference on Acoustics Speech and Signal Processing, 2002In this paper, A review of signal processing for sky wave over-the-horizon radar (OTHR) is presented. The radar's operating mode, and its advantages and limitations are introduced firstly. Then the techniques on interference suppression, correction of some ionospheric contamination, and ship detection are reviewed in detail.

Receive Arrays for Polar Over-the-Horizon Radar
2020 IEEE International Radar Conference (RADAR), 2020Receive array design for Polar Over-the-Horizon Radar is driven primarily by the need to mitigate auroral radar clutter that appears at all azimuth angles. Arrays must be adequate to enable the detection and location of targets in the presence of this clutter.

Over the horizon radar down-under
2015 IEEE Radar Conference (RadarCon), 2015Since the earliest days of military radar application Australia has had a vibrant radar research community, principally in government laboratories. From the 1960's researchers, benefitting from earlier experiments on HF radar detection of missiles, began to plan and implement over-the-horizon radar systems designed for defence surveillance off the ...

Statistical signal processing for application to over-the-horizon radar
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002A review of recent developments in statistical signal processing for application to over-the-horizon radar (OTHR) is presented. Three different signal processing issues are considered. The first two issues relate to the radar interference characterisation, namely a Gaussianity test and a K-distribution test.

Track fusion in over-the-horizon radar networks
Sixth International Conference of Information Fusion, 2003. Proceedings of the, 2003The surveillance picture provided by an Over-The-Horizon Radar (OTHR) is complicated by multipath propagation. Multiple propagation paths can give rise to several distinct tracks for each target. It has been shown that a Multipath Track Fusion (MPTF) algorithm can successfully use both track and ionospheric information to provide a single track per ...

Time Reversed Over-The-Horizon Radar
2011Time reversal can play a significant role in improving the performance of current sky-wave high-frequency over-the-horizon-radar (HF OTHR), especially with respect to real-time monitoring and compensation of ionospheric turbulence. Also, multipath interference arising from an HF OTHR environment can significantly increase resolution and the signal-to ...

DETECTION OF AIRCRAFT USING OVER-THE-HORIZON RADAR
1967Abstract : Tracking of an aircraft flying at an altitude of 100 ft above the sea was accomplished over a radial range interval ranging from 1400 to 1000 naut mi by using the Project MADRE radar. Simultaneous tracking, over part of this range interval, of another aircraft at 10,000 ft illustrates the target altitude independence characteristic of over ...
