Littoral Refractivity Prognostic Advancement

Abstract

The goal of this research is to improve Coupled Ocean/Atmosphere Prediction System (COAMPS(registered) ) to the point that it provides engineering quality refractivity fields in the littorals. These engineering quality refractivity fields will be able to support radio frequency system testing, acquisition, radar system performance forecasts and radar sea and land clutter forecasts. The objective of this research is to improve the Coupled Ocean/Atmosphere Prediction System (COAMPS(registered) ) atmospheric boundary layer (ABL) wind and refractivity field forecasts in the littorals with respect to error threshold requirements established by the chemical sensor testing, propagation, and surface radar sea and land clutter model communities. Assimilation of special field measurements will be investigated with a focus on improving the model forecast refractivity fields. This technology will provide situational awareness of the 3D radio-frequency (RF) propagation environment and a quantitative diagnostic and prognostic capability for assessing sub- and super-refractive conditions in the littorals. The research will lead to the exploitation of anomalous RF propagation fields in order to re-deploy spectrum, sensor, and communications assets to avoid propagation liabilities and to take advantage of propagation opportunities validating with US Naval surface sensor test data.
