FIELD: meteorology, applicable in automatic systems of determination of weather phenomena dangerous to aviation, as well as in other branches of human activity, where the knowledge on the value of the charge of atmospheric aerosol is required.
SUBSTANCE: an acoustic radar with known characteristics (w-the power; f-the frequency of the acoustic wave; τ- the length of the sounding acoustic pulse; Θ-the width of the directional patter of the acoustic radar aerial) excites mechanical vibrations of atmospheric air with a subsequent recording of the electric field strength that is a response of the charged aerosol particles to the acoustic action, and the charge of the aerosol particles of the unit volume is determined according to a definite formula.
EFFECT: remote determination of the charge of aerosol particles in the atmosphere, enhanced volume of the investigated environment and expanded range of measurements in the spectrum of the maximum values.
