SYNTHESIS AND ANALYSIS OF THE TRACKING DEVICE DISCRIMINATOR OF THE ATMOSPHERE RADIO ACOUSTIC SOUNDING SYSTEMS
要約
Features of the radio waves propagation in the atmosphere inhomogeneity induced by the acoustic vibrations are analyzed. Processing methods of the reflected radio signal from the speaker packages making it possible to estimate the air temperature are discussed. Causes of errors arising in the signal processing are analyzed. The correlation processing method that provides high instrument accuracy of the vertical profiles registration of the air temperature at a relatively simple processing device of the scattered signals is discussed. Simplicity of the device is achieved by the operation of the system in the tracking mode for the parameter of the Bragg condition detuning. The feature of the device consists in the use of the estimated parameter value defined in the previous cycle of observation.
