Abstract

The possibilities of the remote detection of continuous the ring laser beam propagating in the scattering continental and coastal atmosphere at its registration in off-axis zone are discussed. In approaching of the single scattering the estimations of the beam radiance in the point of registration are done, these estimations are compared to threshold characteristics of the available photodetectors in visible and infrared spectral range. It is shown, that the beam of laser radiation is reliably registered in the range of scattering angles (0–180)° in meteorological visibility range (5–20) km at night. In the twilight under same conditions the detection possibilities are essentially reduced.
