An interhemispheric, statistical study of nightside spectral width distributions from coherent HF scatter radars [PDF]

, 2002
International audienceA statistical investigation of the Doppler spectral width parameter routinely observed by HF coherent radars has been conducted between the Northern and Southern Hemispheres for the nightside ionosphere.

Spectral analysis in high frequency radar oceanography [PDF]

, 2006
High Frequency radar systems provide a unique opportunity to measure evolving littoral oceanic dynamics at high temporal and spatial resolution. Backscattered electromagnetic signals from ocean waves are modulated by Bragg resonant scattering.

Generation and Assimilation of Propagation Advice for HF Skywave Radar Systems

, 2008
HF skywave (OTH) radars operate in a very challenging environment so the objective of optimizing the radar resources to address the surveillance missions can be achieved only with the aid of a variety of support systems and models.
