Abstract Keywords
The paper is concerned with investigation of power of a
laser target signal from the rough earth surface in hazy
(optically-dense) atmosphere. The paper examines a com-
mon case of bistatic location wherein the transmitter and
receiver of the laser locator are situated in different points
of coordinate space. We found an analytic expression for
the received power of the laser target signal for lighting the
rough surface with local indicatrix of reflection, comprised
of diffuse (wide angle) and quasispecular (narrow angle)
components by a narrow laser beam in turbid medium.
The formula makes it possible to correctly describe the
relationship between the power of the laser target signal
and the distance to surface both in optically-transparent
earth atmosphere (on initial section of location line), and in
optically-dense earth atmosphere (for long distance laser
radar from surface)
Power of laser target signal, rough
surface, hazy atmosphere
