Rijkswaterstaat's interest in HF radar
IEEE Journal of Oceanic Engineering, 1986In 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 ...

HF radar detection of tsunamis
Journal of Oceanography, 2006This paper demonstrates that HF radar systems can be used to detect tsunamis well before their arrival at a coastline. We solve the equations of motion and continuity on the ocean surface using models to simulate the signals produced by a tsunami approaching the east U.S. coast.

Abstract : Interference to communication reception near an HF radar is dependent on many factors. It is shown that the most important of these that can be controlled is the pulse shape of the radar. Under optimum conditions, acceptable reception should be possible with frequency separation as little as 21 kHz from the proposed radar.

Abstract This paper provides an overview of six poster presentations contributed to the Open Symposium on Active Experiments in Space Plasmas at the XXIst General Assembly of URSI. The six poster presentations deal with HF ionospheric modification and are primarily experimental in nature.

Sixth International Conference on `HF Radio Systems and Techniques', 1994
HF over-the-horizon radars often use CW transmissions comprising repeated linear FM sweeps. The resolution and sidelobe performance in the range dimension are determined within each sweep, but Doppler information is extracted by processing together the outputs of a number of sweeps.
