The invention relates to radio-location meteorology, in particular to radio-acoustic methods for measurement of parameters of atmosphere, and can be used at compilation of short-term weather forecasts, at meteorological provision of ecologic monitoring of atmosphere and safety of take-off and landing of aircrafts for different purposes, at compilation of radio-climate maps, etc. The method of radio-acoustic sounding of atmosphere for remote registration of vertical profile of air temperature is in fact that one radiates vertically upwards an acoustic pulse with sinusoidal filling, one radiates acoustic pulse with electromagnetic vibrations with wavelength twice larger than wavelength of sinusoidal filling of acoustic pulse, one receives electromagnetic oscillations scattered with acoustic pulse, with multiplication in sequence of output signal of radio-receiver from each level of sounding track with signal of each of 1, 2, … N support generators, with comparison to each other of amplitudes of output signals of correlation device from each level of sounding track and with determination of maximal one of those. Support signals for correlation reception are formed according to dissipation function for each level of sounding track, at that by maximal value of amplitude of output signal of correlation device from each level of sounding track one determines parameter of unbalancing of Bregg’s condition q for each level of track of sounding that is used for calculation of air temperature for all points of vertical profile of air temperature. Calculation of air temperature with use of value of unbalancing of Bregg’s condition gives possibility of obtaining increased accuracy of registration of vertical profile of air temperature with radio-acoustic sounding without fulfillment of Breggs condition at sounding track. |
