The estimation of radio-waves multibeam propagation effect in tropospheric waveguides (ТWG) over sea water area on quality parameters of air objects detection is conducted. It is shown, that the tropospheric waveguide is a fading channel. For definition of signals statistical characteristics on the receiving device input, ТWG is presented in the form of an equivalent multiterminal network with casual transfer factor. Analytical expression for amplitude probability density of the radar signal reflected from air object in a tropospheric waveguide over a sea surface, on the input of radar receiving device is received. Curves for such signal detection are built.
quality parameters of detection, a tropospheric waveguide, not rectilinear propagation of radio-waves
