METHOD OF DETERMINATION OF STATE OF ATMOSPHERE Russian patent published in 1997 - IPC

FIELD: radiolocation meteorology. SUBSTANCE: observed section of atmosphere is irradiated with first radiolocation pulses of linear polarization, reflected signals of same polarization are received, ratio of power of received signal to power of inherent noises of receiver is measured with subsequent calculation of radiolocation reflectance Z_l of observed section of atmosphere, observed section of atmosphere is irradiated with second radiolocation pulses of circular polarization, reflected signals of same polarization are received, ratio of power of received signal to power of inherent noises of receiver is measured with subsequent calculation of radiolocation reflectance Z_c of observed section of atmosphere. First and second radiolocation pulses of linear and circular polarization are emitted in sequence, received reflected signals corresponding to first and second radiolocation pulses are separated with formation of two sequences of reflected signals. Values Z_l and Z_c are determined by average values of received reflected signals and ratio and absence or presence of hydrometers and radioactive additives is ascertained by values of K, Z_l and Z_c. EFFECT: increased operational authenticity of method. 1 dwg
