FIELD: optical detection and ranging. SUBSTANCE: sending of light pulses of different duration is accomplished from not less than three points confined between boundary points of specified section of atmosphere along this section. Echoes are received from same volumes of atmosphere and are differentiated by duration of pulses. EFFECT: enhanced accuracy of determination of attenuation factor. 1 dwg
