Brightness Fluctuations of the Sunny-Path Image Depending on the Sharpness Setting of the Observation-System Lens

  • Published:
Radiophysics and Quantum Electronics Aims and scope

We theoretically study the variation coefficient of the solar radiation reflected from a wavy sea surface as a function of the range to which the observation-system lens is focused. During the study, we revealed the possibility of existence of two different regimes of the received-signal fluctuations, namely, the single- and double-hump dependences of the variation coefficient on the lens-adjustment range. The effect of splitting one maximum of the variation-coefficient dependence on the range into two maxima is explained within the framework of simple optical models.
