Sea-Clutter and Collision

Multifractal features of sea clutter

Sea clutter refers to the backscattered returns from a patch of the sea surface illuminated by a transmitted radar pulse. Since the complicated sea clutter signals depend on the complex wave motions on the sea surface, it is reasonable to study sea clutter from nonlinear dynamics, especially chaos, point of view, instead of simply based on random processes. In the past decade, Dr. Simon Haykin’...

Discrimination between Weather and Sea Clutter

The results of automatic discrimination between weather and sea clutter using S-band dual-polarization Doppler weather radar are presented. The data were collected with the NCAR SPOL radar located in the Pacific shoreline near Seattle, USA. The multiparameter dataset includes backscattered power P (or radar reflectivity Z), Doppler velocity V, spectrum width σv, differential reflectivity ZDR (p...

Scattering Physics of Multistatic Radar Sea Clutter

Small Target Detection in Heavy Sea Clutter

This paper mainly deals with the detection problem of the target with low Radar Cross-Section (RCS) in heavy sea clutter with unknown Power Spectral Density (PSD). Since the performance of traditional single-scan detectors degrades as the target of interest is smaller and weaker, three adaptive detectors, based upon a two-step design procedure, are proposed within the framework of the multiples...

High Grazing Angle Sea-Clutter Literature Review

This report reviews the published literature on the characteristics of mono-static radar seaclutter observed with high grazing angles (typically above about 10). To date, most of the analysis and modelling of sea-clutter has been undertaken at low grazing angles with the main application being for surface and airborne maritime radars. The report identifies some of the data sets that have been ...
