Parameterization of Near-Surface Refractivity Profiles Over the Ocean and their Effects on IR/Rf Propagation
نویسندگان
چکیده
The long-term goal of the Naval Postgraduate School’s research effort is to improve parameterizations and operational models that describe atmospheric and surface wave effects on radar and optical sensor/weapons systems, which will ultimately benefit U.S. Navy warfighters in planning and executing operations by improving sensor performance and target detection predictions and sensor optimization for the current environment.

Electrooptic Propagation
The EO Propagation objectives are: 1) investigate, develop and evaluate fine and coarse mode aerosol models and their effects on visibility and target detection in visible and IR wavelengths 2) Integrate and develop simple, realistic extinction, scintillation and refractivity models for infrared propagation near the ocean surface, 3) develop and evaluate advanced marine radiance models that are...
متن کاملEstimation of Radio Refractivity Structure Using Matched-Field Array Processing
In coastal regions the presence of the marine boundary layer can significantly affect RF propagation. The relatively high specific humidity of the underlying “marine layer” creates elevated trapping layers in the radio refractivity structure. While direct sensing techniques provide good data, they are limited in their temporal and spatial scope. There is a need for assessing the three-dimension...
متن کاملTowards assimilation of atmospheric surface layer using numerical weather prediction and radar clutter observations
Radio wave propagation on low-altitude paths over the ocean above 2 GHz is significantly affected by negative refractivity gradients in the atmospheric surface layer (ASL) which form what is often referred to as an evaporation duct (ED). Refractivity from clutter (RFC) is an inversion approach for estimation of the refractivity profile from radar clutter, and RFC-ED refers to its implementation...

متن کاملInversion for refractivity parameters from radar sea clutter
[1] This paper describes estimation of low-altitude atmospheric refractivity from radar sea clutter observations. The vertical structure of the refractive environment is modeled using five parameters, and the horizontal structure is modeled using six parameters. The refractivity model is implemented with and without an a priori constraint on the duct strength, as might be derived from soundings...
