High Frequency Ground Wave Radar (HFGWR) target tracking is a challenging task because of dense false alarms and missed/disturbed measurements caused by strong sea clutter. A clutter-knowledge-based tracking method is presented to cope with multi-target tracking in this kind of complex envionment. Modified initiation methods based on characterestic anslysis of multiscan asssociation results are proposed...
To study information fusion method under complex environment, a highly intelligent information fusion model is put forward- the NFE model. This model is an organic combination of neural network, fuzzy reasoning and expert system. Considering various factors which influence the performance of sensor, the NFE confidence estimator is presented from the engineering application point of view. This paper...
Serious radio interferences are distributed in the operating frequency band of High-frequency surface-wave radar (HFSWR) which makes it difficult to find silent bandwidth especially at night to work, the performance of HFSWR is decreased greatly. Frequency randomly hopping signal which breakthrough the restriction of continual spectrum has become an effective anti-jamming method. Based on the study...
