High Grazing Angle Sea-Clutter Literature Review
نویسندگان
چکیده
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 collected and the empirical models that have been developed from them for the normalised radar cross-section. The amplitude statistics and Doppler spectra of high grazing angle clutter are reviewed and the implications for radar design and target detection are discussed.

Effect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection
Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...
متن کاملAn Investigation of the Pareto Distribution as a Model for High Grazing Angle Clutter
The Pareto Distribution is proposed as a new model for high resolution, high grazing angle radar sea clutter returns. It is assessed using the Ingara radar clutter gathered in 2004. Included is range profile modelling as well as global distributional fitting to clutter streams. APPROVED FOR PUBLIC RELEASE
متن کاملHigh Grazing Angle and High Resolution Sea Clutter: Correlation
Spatial and temporal correlations of high grazing angle high resolution sea clutter collected by the DSTO Ingara polarimetric X-band system are studied. It seems that wavelengths of wind waves and swells are retrievable from the range correlation whereas the periods of the waves and swells are recoverable from the azimuthal correlation. The polarimetric behaviour of sea clutter is also studied,...
متن کاملDistribution of X-Band High Resolution and High Grazing Angle Sea Clutter
This report studies the spatial distribution of X-band, high resolution and high grazing angle polarimetric sea clutter data. The K distribution usually provides a good fit for the distribution of the VV polarised data. The HH polarised data is spikiest and its distribution exhibits a sudden departure from the K distribution in the tail region, which usually requires the KA or the similar distr...
متن کاملMeasured forward-scatter sea clutter at near-zero grazing angle: analysis of spectral and statistical properties
To develop forward-scatter radar (FSR) systems for use in maritime applications, a fundamental understanding of the operating environment is required. Currently, there is a lack of published experimental FSR sea clutter data at very low (near-zero) grazing angle over the sea. This data is necessary for the development of FSR systems for maritime applications. Therefore to facilitate further inv...
