Globally Conditioned Conditional FLOW (GCC-FLOW) for Sea Clutter Data Augmentation

open access: yesApplied Sciences
In this paper, a novel deep learning approach based on conditional FLOW is proposed for sea clutter augmentation. Sea clutter data augmentation is important for testing detection algorithms for maritime remote sensing and surveillance due to the ...

Analysis of spatial point process characteristics of radar detections in sea clutter region

open access: yes2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
In this paper, sea clutter radar plots are modeled by spatial point processes. A test procedure is proposed to analyze “Complete Spatial Randomness (CSR)” characteristics of radar plot locations. Plot intensity map is also constructed. This map is separated into two sub-regions; cutter region and moving target region.

A Novel Method of Small Target Detection in Sea Clutter [PDF]

open access: yes, 2011
Detecting low observable targets within sea clutter at low grazing angle is one of the research hotspots in radar signal processing community. In this paper, we have proposed a novel method based on polarimetric decomposition theorem.

A Novel Main-Lobe Cancellation Method Based on a Single Notch Space Filter and Optimized Correlation Analysis Strategy

open access: yesInternational Journal of Antennas and Propagation, 2019
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.

DSIM: A DisSIMilarity-based image clutter metric for targeting performance

open access: yes, 2013
Previous image clutter metrics were proposed on the thought that clutter was just a perceptual effect, while we identify clutter as both perceptual and cognitive effects.

Amplitude Suppression of Nongaussian Sea Clutter in a Coherent Bandpass Path of the Receiver

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2016
The method of non-linear amplitude suppression of radar clutter from a sea surface in the coherent band path of the receiver is considered. The model of the most adequate nongaussian radar clutter from the rough sea surface which envelope is based on K ...

Feature Congestion and Subband Entropy measures of visual clutter

open access: yes, 2007
This MATLAB software implements two measures of visual clutter described in our Journal of Vision 2007 paper in the special issue on crowding. The remaining measure described in that paper, Edge Density, is only two lines of MATLAB code and is fully ...
