Estimation Of Radio Wave Propagation Conditions Above The Sea Surface By Radiometric Measurements At Grazing Angles

摘要

Basing on the results of investigations the method for estimation of radio wave propagation conditions above the sea surface is offered. The method is based on the radio brightness temperature measurements at the grazing angles. For estimation the parameters of the radio brightness temperature elevation profile on the vertical polarization, well correlating with radio wave propagation conditions on beyond-line-of-sight paths are used. As far as the relative measurements are used, the requirements to radiometer stability are reduced.
