چکیده
In this paper, a method for estimating atmospheric refractivity from sea and land clutters is proposed. To estimate the refractivity, clutter power spectrums based on an artificial tri-linear model are calculated using Advanced Refractive Prediction System (AREPS) simulator. Then, again obtained measured data AREPS actual operation, spectrum reflectivity can be replaced with real-time collected radars. A cost function genetic algorithm (GA) then defined difference between two to predict model. The optimum variables of determined at minimum in GA process. results demonstrate that predicted proposed powers.

Effects of Sea Clutter on Atmospheric Refractivity Estimation
This paper addresses the effects of sea clutter on the clutter-based atmospheric refractivity estimation techniques. It provides a mean square error (MSE) metric for refractivity estimators based on the available clutter-to-noise (CNR) ratio, the type of the sea clutter statistics (Rayleigh, K-distributed and log-normal) and the parameters forming these probability density functions (pdf) such ...
متن کاملRefractivity estimation from sea clutter: An invited review
[1] Non‐standard radio wave propagation in the atmosphere is caused by anomalous changes of the atmospheric refractivity index. In recent years, refractivity from clutter (RFC) has been an active field of research to complement traditional ways of measuring the refractivity profile in maritime environments which rely on direct sensing of the environmental parameters. Higher temporal and spatial...
