FEATURES OF ENERGY ACCOUNTING OF ELECTRO-OPTICAL SYSTEMS OF UNDERWATER OBJECT DETECTION IN THE PRESENCE OF SOLAR PATH
Calculation of illumination in the water column that is the part of energy calculation of electrooptical system (EOS) of undersea object (UO) detection in the presence of “solar path” is considered. Taking into account of “solar path” phenomena in energy calculation may to considerably influence on technical characteristics for such EOS. Calculation for case of undersea EOS placement is taking as basic. Possibility to use of this calculation for case of aircraft side EOS placement and observation of UO through the sea surface is analyzed. Computational modeling of illumination in the water column with taking into account of “solar path” component and component of forward diffuse radiation is carried. It is display that the received results of calculation of “solar path” illumination component are considerably understated in comparison with results of calculation of water column illumination without “solar path” phenomena. It is identify that the main cause of this disagreement is the imperfection of accounting of rough sea phenomena influence on optical transmission through the surface “air-water”. Further direction of study is associated with improvement of accounting of this influence.
Keywords: “solar path”, illumination in the water column, detection of undersea objects
