Методи і засоби обробки та вимірювання частоти заповнення ехосигналів доплерівського лага

Abstract

The thesis is dedicated to the relevant scientific problem of improving the metrological parameters of methods and means of processing and measuring basic frequency of echo-signals of Doppler Log. The thesis introduces the theoretical generalization and the new ways of solving the scientific problem, providing radio frequency measurements of Doppler frequency shifts. The frequency measuring method by means of timing fragmentation of echo-signals has been worked out. The method of tracking narrow-band filtering has been improved. The mathematical model has been modified and the computer physical modeling of Doppler signals has been performed.The flow charts of means of preprocessing and measuring of carrier frequency have been developed. Analytic dependencies have been obtained and the errors in the designed methods of measuring carrier frequency of echo-signals have been analyzed, their quantitative assessment in terms of theoretical and experimental research having been performed.
