Study of EM Signals Propagation Through Marine Atmospheric Boundary Layer and Static Pressure Measurements in Marine Atmospheric Boundary Layer During CBLAST.

摘要

Radio tracking, communications and guidance at sea rely on interpreting of radar signals. This has motivated extensive studies of the physical factors governing the pattern of signal propagation over the ocean. Although over the last several decades the models of electromagnetic propagation have been substantially advanced (Kukushkin (2004); Levy (2000)), measurements and modeling results still show differences that can distort signal interpretation. In particular, signal intensity at the receiver is often over-predicted by models (Barrios and Patterson (2002)), which suggests that mechanisms of signal energy loss are still incompletely understood and/or are not correctly built into the propagation models. The long-term goal of this work is to identify the source of discrepancies between observations and propagation model predictions and update the models so that the discrepancies are reduced.
