Abstract EN
The high-frequency hybrid sky-surface wave radar (HFSSWR) is a new kind of over-the-horizon radar system.
Combining the advantages of both the sky wave radar and the surface wave radar, HFSSWR has drawn much attention in recent years.
But the new system also brings new challenges.
One of the most severe problems is that the heterogeneous environment makes a big challenge for the sea clutter suppression processing.
Due to the nonstationary properties of the ionosphere, the first-order sea clutter statistics change significantly among range bins.
So the new efficient sea clutter suppression method is required, and the clutter characteristics analyses are also in urgent need of research in order to guide the design of the algorithm in the background of HFSSWR.
In this paper, utilizing the measured data set, we first analyse the range and spatial characteristics of the nonhomogeneous first-order sea clutter in HFSSWR.
Then, an improved main-lobe cancellation (IMLC) method based on single notch space filter and correlation analysis is proposed to get training data which contains precise clutter information.
A main-lobe clutter canceller based on the single notch space filter has been developed to block the target component, and an optimized correlation analysis (OCA) strategy is presented to choose the efficient training data.
Finally, the method is examined by measured data and the results indicate that the method has a good performance for broadening first-order sea clutter suppression than the traditional method.
