Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR
In addition to target echoes, high frequency surface wave radar (HFSWR) receives sea and ionospheric clutter. Among these clutters, the ionospheric clutter is dominant and significantly affects the detection performance of HFSWR, particularly when the ...
