Finland HF and Esrange MST radar observations of polar mesosphere summer echoes [PDF]
Annales Geophysicae, 2003 Peculiar near range echoes observed in summer with the SuperDARN HF radar in Finland are presented. The echoes were detected at four frequencies of 9, 11, 13 and 15 MHz at slant ranges of 105–250 km for about 100 min.

Estimating Coastal Winds by Assimilating High-Frequency Radar Spectrum Data in SWAN
Sensors, 2021 Many activities require accurate wind and wave forecasts in the coastal ocean. The assimilation of fixed buoy observations into spectral wave models such as SWAN (Simulating Waves Nearshore) can provide improved estimates of wave forecasts fields.

HF radar backscatter inversion technique [PDF]
Radio Science, 2006 Methods of inverting high‐frequency radar land and sea backscatter to obtain ionospheric vertical profiles offer an important means of remote sensing the ionosphere up to thousands of kilometers from the transmitter/receiver location. This new inversion technique requires the received elevation angle as well as the time delay or group path of the ...
