Waveform Design Based on Environmental Sensing for Sky-Wave Over-the-Horizon Radar
2015 IEEE Radar Conference (RadarCon), 2015Sky-wave over-the-horizon (OTH) radar operates in the high-frequency (HF) band congested by external interferences. Owing to the serious occupancy, sometimes OTH radar cannot find suitable clear channel with sufficient bandwidth, especially when broad band is needed.

In sky-wave over-the-horizon radar (OTHR), it is quite difficult to handle the issues of target location (ground range) and height (altitude) estimation due to their joint effect on group range. This work addresses the joint estimation of target location and height by the means of multipath propagation of OTHR signals and structure of a two-dimensional

We propose an approach to the problem of range coordinate registration (CR) for HF band over-the-horizon sky-wave radar (OTHR-SW) signals on a single pulse basis. The approach is based on the a priori knowledge of the displacement of the sea/land transitions within the area illuminated by the radar antenna beam.

A Two-hierarchy Hough Transform Based Track Initiation Method for Sky-wave Over-the-Horizon Radar
Journal of Electronics & Information Technology, 2011The 3L (low data sampling rate, low measurement precision and low detection probability) features of sky-wave Over-The-Horizon Radar (OTHR) pose new challenges to the conventional track initiation methods. In this paper, a Two-Hierarchy Hough Transform track initiation method (TH-HT) is proposed.

Target detection method in short coherent integration time for sky wave over-the-horizon radar
Sādhanā, 2020In order to reduce the Doppler spread effect caused by ionospheric disturbance, sky wave over-the-horizon radar often detects ships in a short coherent integration time (CIT). In short CIT, an effective means to detect ships is clutter suppression. Through the analysis of the real data, it is found that the sea clutter has a strong correlation when the

Over the Horizon Sky-wave Radar: Coordinate Registration by Sea-land Transitions Identification
2009In this paper, we propose an approach to the problem of real time coordinate registration for Over the Horizon Sky Wave signals. The approach is based on the a priori knowledge of the displacement of the sea-land transitions within the radar coverage area, namely, takes advantage of the geo-morphological structure of the surveillance area, employing it
