Generation of interference in the surface layer at horizontal sounding of sea surface by infrared sight channels and devices

Abstract

Object and purpose of research. The object of investigation is specific temperatures at the water/air interface (skin layer of water). The purpose is to study the interrelation of dynamics in humidity variations of surface atmospheric layer and particulars of the media interface. Subject matter and methods. Infrared thermal imagers are employed with monitoring of the parameters of atmospheric layer adjacent to ocean surface using a multi-channel thermal hygrometer and contact temperature sensors placed in water and near-water air layer. Laboratory rigs of different scales simulating various levels of external factors and an open water basin were used. Main results. Consistent analysis is done regarding phase-wise measurement of skin water layer characteristics, specific structure of temperature field in IR band of spectrum under laboratory and large-scale conditions, variations of humidity content at different state of skin water layer in the process of interaction between two media. Measurements of the radiation fog of different scales are taken, which possibly forms the false and real horizons being one of the interferences for transmission of IR radiation to recording channels. Parameters and specific manifestation of this interference are measured. Conclusion. Based on the analysis and experiments it is confirmed that there are abnormal localizations of humidity content of different scales, which produce radiation temperature variations.
