Applications of high‐frequency radar [PDF]
Radio Science, 1998 Efforts to extend radar range by an order of magnitude with use of the ionosphere as a virtual mirror started after the end of World War II. A number of HF radar programs were pursued, with long‐range nuclear burst and missile launch detection demonstrated by 1956.

Sampling criteria for mutual over‐the‐air synchronisation of radar sensors
Electronics Letters, 2021 Synchronisation of radar systems can be used to suppress interference and enable communication between radars. In this paper, a generalised Kuramoto model is proposed, which can be used to synchronise pulse repetition frequencies of two radars over‐the ...

High-frequency radar-derived coastal upwelling index
State of the Planet, 2023 Abstract. Coastal upwelling has been extensively studied since it plays a critical role in the connectivity between offshore waters and coastal ecosystems, which has impacts on water quality, fisheries, and aquaculture production. Significant efforts have been devoted to the quantification of the intensity, duration, and variability of this phenomenon ...
