Le fouillis ionosphérique dans le radar à ondes de surface à haute fréquence (HFSWR) est la réflexion des ondes électromagnétiques de l'ionosphère vers le récepteur, qui doit être supprimée autant que possible dans le but principal de détection de cible dans le HFSWR. Cependant, le fouillis ionosphérique contient de grandes quantités d’informations sur l’état de l’ionosphère. En étudiant le fouillis ionosphérique, certains des paramètres ionosphériques pertinents peuvent être déduits, en particulier pendant la période des typhons, lorsque l'état de l'ionosphère change de manière drastique, affecté par les ondes de gravité excitées par les typhons, et en utilisant les caractéristiques temps-fréquence du fouillis ionosphérique au moment du typhon. des informations telles que la tendance des changements de concentration électronique dans l'ionosphère et la direction du typhon peuvent être obtenues. Les résultats du traitement des données radar ont montré l’efficacité de cette méthode.

Abstract: The ionospheric clutter in High Frequency Surface Wave Radar (HFSWR) is the reflection of electromagnetic waves from the ionosphere back to the receiver, which should be suppressed as much as possible for the primary purpose of target detection in HFSWR. However, ionospheric clutter contains vast quantities of ionospheric state information. By studying ionospheric clutter, some of the relevant ionospheric parameters can be inferred, especially during the period of typhoons, when the ionospheric state changes drastically affected by typhoon-excited gravity waves, and utilizing the time-frequency characteristics of ionospheric clutter at typhoon time, information such as the trend of electron concentration changes in the ionosphere and the direction of the typhoon can be obtained. The results of the processing of the radar data showed the effectiveness of this method.
