The invention relates to radio-location meteorology, in particular to radio-acoustic devices for measurement of parameters of atmosphere. Device for remote determination of humidity of atmospheric air includes connected in sequence support high frequency generator and radio transmitter first output of which is connected to transmission radio-antenna, and second is connected to first input of radio-receiver, second input of radio-receiver is connected to output of receiving radio-antenna, and output of radio-receiver is connected to input of frequency measuring device, generator of acoustic frequency one output of which is connected to input of amplifier of acoustic frequency, and second output of generator of acoustic frequency is connected to input of transformer of acoustic frequency output of which is connected to first input of amplifier of doubled acoustic frequency, it includes as well acoustic antenna, frequency transformer output of which is connected to controlled phase changer output of that one is connected to first input of phase change measuring device, first output of micro-computer is connected to frequency measuring device, its second input is connected to input of phase shift measuring device, and third and fourth inputs of micro-computer are connected to first inputs of amplifier of acoustic frequency and amplifier of doubled acoustic frequency. To device antenna switch ios included, first and second acoustic receivers, at that first input of antenna switch is connected to acoustic antenna. Second and third inputs of antenna switch are connected to outputs of amplifier of acoustic frequency and amplifier of trim frequency, fourth input of antenna switch is connected to fifth output of micro-computer, first output of antenna switch is connected to input of acoustic antenna, second input of antenna switch is connected to input of first acoustic receiver output of which is connected to input of transformer, and third output of antenna switch is connected to input of second acoustic receiver output of which is connected to input of transformer and third output of antenna switch is connected to input of second acoustic receiver output of which is connected to input of phase shift measuring device. The invention provides increase of accuracy of determination of accuracy of measurement of humidity of atmosphere and decrease of expenses for obtaining information on humidity. |
