Sky-wave OTHR ionospheric channel simulation
IET International Radar Conference 2013, 2013A new simulation method for sky-wave OHTR ionospheric channels is developed. To make the simulation more robust, the International Geomagnetic Reference Field (IGRF) model and International Reference Ionosphere (IRI) model are integrated with a classical 3D ray tracing code firstly.

Piecewise adaptive beamforming method with multiple constraints for OTHR
IET International Radar Conference 2013, 2013The coherent processing interval in Over-The-Horizon Radar (OTHR) is usually set long to strengthen the weak signals, which increases the nonstationarity of the inference and make it more difficult to be restrained. In this paper, a piecewise beamforming method using multiple constraints to hold the coherence of the clutter is proposed.

OTHR multipath tracking with uncertain coordinate registration
IEEE Transactions on Aerospace and Electronic Systems, 2004Multipath probabilistic data association (MPDA) exploits discrete multipath propagation to improve tracking performance for systems such as over-the-horizon radar (OTHR). The original formulation assumed a known ionospheric environment for mapping radar measurements to ground coordinates.

Transient Interference Excision in China Experimental OTHR
Revue de l'Electricité et de l'Electronique, 2005Le radar transhorizon a onde de ciel recherche les cibles apres reflexion sur l'ionosphere. Il est dote d'une grande portee et couvre une large zone, mais il recoit de forts echos du terrain et de la mer, et il est soumis a de fortes interferences : interferences radiofrequences, bruit industriel, bruit impulsif, echos sur les trainees meteoriques, etc.
