The processing of HF skywave radar signals

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
This paper presents an overview of a significant and computationally demanding application of signal processing, viz. over-the-horizon radar (OTHR). The Jindalee Operational Radar Network is an integrated network of OTHRs which depend heavily for their performance, in both air and surface mode, on signal processing.

Ionospheric probing with an HF radar

Electronics & Communication Engineering Journal, 1989
The Jindalee over-the-horizon (OTH) radar is designed primarily for extended air defence surveillance of Australia's northern coastline. It achieves its long-range capability by employing ionospheric reflection. This use of the ionosphere allows the radar to have a powerful secondary role in remote sensing because information about the ionosphere can ...

HF Ocean Radars in Ship Navigation

2018 IEEE 27th International Symposium on Industrial Electronics (ISIE), 2018
Phased HF ocean radar technology is being widely used for surface current mapping in coastal waters, and the WERA radar produces gridded maps of surface currents and wave heights. These data can be put into existing AIS ship navigation messages to provide Aid to Navigation information to ship's bridges in coastal waters.

Rijkswaterstaat's interest in HF radar

IEEE Journal of Oceanic Engineering, 1986
In this paper an explanation is given of Rijkswaterstaat's need for hydrological and meteorological information. The present means to gather this information are described together with their limitations. Future developments in the field of HF narrow-beam groundwave radar systems are indicated and some recommendations are given for the design of an ...
