Abstract :
In this paper, the mechanism and form of ionospheric multipath effect in skywave over-the-horizon radar has been described firstly. According to its various forms, a scheme based on validating region adaptive determination and energy-weighted data association in data processing algorithm has been proposed to eliminate the multipath effect, and its performance is evaluated simply. In an integrated simulation environment, elimination scheme is tested and verified. The simulation results and analysis are also given, and finally some valuable conclusions on practical application are drawn
