Research on Sea Clutter Suppression Using Sparse Dictionary Learning

2019 IEEE 8th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2019
Due to the interference of the strong sea clutter, it’s difficult to detect marine weak targets and clutter attenuation is the key to improve detection performance. A sea clutter suppression method based on sparse dictionary learning was proposed to attenuate sea clutter and thus enhance the detection performance.

Ionospheric Decontamination and Sea Clutter Suppression for HF Skywave Radars

IEEE Journal of Oceanic Engineering, 2005
In this paper, a cascaded correction and suppression method of reducing ionospheric phase path contamination and sea clutter to enable detection of targets travelling at speeds near the Bragg Doppler is addressed. The Hankel rank reduction (HRR) technique based on singular value decomposition (SVD) has been used to estimate the ionospheric phase ...

Suppression of Sea Clutter of Skywave Radar Based on AR Model

Applied Mechanics and Materials, 2012
The prediction of chaotic time sequence based on AR model is studied. The forming mechanism of the first-order Bragg lines of sea clutter is analyzed. According to the signal characteristic of sea clutter, a sea clutter time sequence predictor and a skywave radar sea clutter suppression system based on AR model are presented.

Using SVD-FRFT Filtering to Suppress First-Order Sea Clutter in HFSWR

IEEE Geoscience and Remote Sensing Letters, 2017
This letter presents a novel signal processing method for HF surface wave radar that offers a solution to suppress significant sea clutter interference. Conventional clutter rejection methods, when the target signal and first-order sea clutter are mixed in the Doppler spectrum, tend to eliminate both the target signal and clutter without distinction ...

Suppression of sea clutter and detection of small ship observed by an S‐band Radar

Electronics and Communications in Japan, 2018
AbstractI have observed sea clutter including a target (small ship) using an S‐band radar with a frequency of 3.05 GHz, a beamwidth of 1.8°, a pulsewidth of 0.5 μs, and a pulse‐repetition frequency of 1600 Hz. To investigate the sea clutter amplitude statistics, I introduce the Akaike Information Criterion (AIC).
