Auto ship detection for high frequency (HF) skywave over-the-horizon (OTH) radar, being a valuable application, has not been achieved virtually within short coherent integration times (CITs). Because the ships' lines in the spectrum can be covered by the ocean clutter's easily as a result of the poor resolution, which attenuates the validities of ocean clutter suppression algorithms. Besides, when...
To detect ship targets within short coherent integration time (CIT), the ocean clutter suppressing technique has been used in high frequency (HF) skywave over-the-horizon-radar (OTHR). The clutter cancellation methods in time field are affected by estimate precision of frequency, amplitude and phase. The methods based on subspace are limited by the difficulty in determining the order of clutter subspace,...
