FIELD: physics.
SUBSTANCE: in order to determine the value of attenuation of radar radiation in a test cloud medium, the cloud medium is probed at given radiation frequency. The reflected signal is received, during processing of which the distance to the imaginary plane passing through the maximum radar echo is determined and dimensionless amplitude is determined. The value of the maximum dimensionless amplitude of the radar radiation is then calculated from the measurement results of parametres of the reflected signal. Further, coherent signal processing employed. The extent of projections of envelops on the axis of distances in each semi-interval is then determined from the screen of the radar. The value of attenuation of the radar radiation is then determined.
EFFECT: high accuracy of measuring attenuation of radar radiation.
