METHOD OF MEASUREMENT OF CLOUD ENVIRONMENT REFLECTANCE Russian patent published in 2009 - IPC G01S13/95 

FIELD: radio engineering.

SUBSTANCE: there performed is the following: radar probing of cloud at specified length of wave, receiving of signal reflected from local explored area of environment and signal display at radar screen in shape of envelope curve with further incoherent processing of this signal by means of measurement of maximum amplitude of curve (Z_R) and distance (R) to this amplitude. Then according to results of incoherent processing of signal, maximum range of instrument contact (R_max.1) is determined. After this coherent processing of video signal is performed in addition and thus maximum range of instrument contact (R_max.2) and corrective multiplier (K) are determined as ratio of obtained values R_max.1 and R_max.2. Then geometrical way (R_max.g) as product of obtained value R_max.1 by corrective multiplier (K) and true value of radar reflectance are determined by formula

where C_λ - radar constant.

EFFECT: increase of accuracy of measurement of cloud environment radar reflectance.
