METHOD OF MEASUREMENT OF ELECTRO-MAGNETIC DENSITY OF CLOUD ENVIRONMENT Russian patent published in 2009 - IPC G01S13/95 

FIELD: radio engineering.

SUBSTANCE: invention may be used for determination of electro-magnetic density of cloud environment in order to determine physical characteristics of environment. The following is performed: 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 by means of simulation of local motion of explored area along range axis. Then according to ratio of video signal parametres before and after motion, maximum range of instrument contact (R_MAX.2) is determined. After this determination of geometrical way (R_max.g) corresponding to maximum range of instrument contact (R_MAX.2) and electro-magnetic density of cloud environment (D) corresponding to it is performed by formula

where R_e - unit distance equal to 1 km.

EFFECT: increase of accuracy of required parametres measurement.
