Abstract

It is demonstrated how the energy is redistributed and the law of conservation of energy is fulfilled when optical radiation reflecting in a turbulent atmosphere. It is found that the mean intensity of an optical beam, scattered by a point reflector or by an ensemble of point reflectors in a turbulent atmosphere, increases in the strictly backward direction (backscatter amplification (BSA) effect) at the expense of overflow of the energy from a huge area several orders of magnitude exceeding the BSA effect localization area.
