Proceedings of 2011 IEEE CIE International Conference on Radar, 2011
In order to effectively detect moving target in strong sea clutter, a detection algorithm for moving target based on clutter map cancellation in fractional Fourier transform (FRFT) domain is proposed. Radar data in FRFT domain are noncoherently accumulated with the single pole feedback clutter map (SPFB-CM) in FRFT domain, which are used to suppress ...

Two-Stage Collaborative Sea Clutter Suppression Based on Subregion Gazing and Reconstruction
IEEE Geoscience and Remote Sensing LettersRadar target detection is an important technical means for effective monitoring of sea surface targets. Under strong sea clutter, the echo characteristics of some targets with small radar cross sections (RCSs) may be submerged, affecting the performance ...

Suppression of Sea-ice Clutter Observed by a Millimeter Wave Radar
International Journal of Infrared and Millimeter Waves, 2007Sea-ice clutter was measured using a millimeter wave radar (MWR) with a frequency of 34.86 GHz, the beamwidth of 0.25° and pulsewidth of 30 ns which is located at Mombetsu in Hokkaido, Japan. In this paper, targets are an iron tower and a breakwater which are embedded in sea-ice clutter.

Suppression of Sea Clutter of Skywave Radar Based on AR Model
Applied Mechanics and Materials, 2012The 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.

An Alternating Proximal Method for Sea Clutter Suppression in Over-the-Horizon Radar Systems
IEEE Geoscience and Remote Sensing LettersThe over-the-horizon (OTH) radar systems are seriously affected by sea clutter. The precise estimation of sea clutter covariance (SCC) plays an important role in suppressing the sea clutter, especially in the case of limited samples.

Sea Clutter Suppression Based on Radon Transform at High Grazing Angles
2006 CIE International Conference on Radar, 2006During final guidance, as radar working over sea surface at a very high grazing angle, it is hardly to distinguish target from clutter background due to the strong reflection of the sea surface. A novel method is presented to suppress the sea clutter in this paper. The proposed method based on Radon transform utilizes edge detection technique to find a
