Device to Determine the Phase Structure of a Radio Signal
Abstract
Purpose: Identifying complex radio signals in real time requires a large assortment of devices which allow you to determine their fine structure both in time and frequency domains. The aim of this work is the development and technical implementation of a realtime algorithm for signal processing which would allow you to unambiguously determine the phase structure of the signals in a wide range of phase angles. Results: On the base of a new signal processing algorithm, a block diagram of the device was developed, and the characteristics of its main functional units have been determined. To reduce the energy dependence of the device, some modern achievements of acoustoelectronics were used. A new topology is developed for elements on surface acoustic waves, providing differentiation, integration, and Hilbert conversion of the input signals in the time domain. A device has been implemented with a relative bandwidth of 30%. Results of the experimental studies are presented, convincingly confirming the theoretical conclusions. Practical relevance: The designed device can uniquely determine the phase structure of radio signals with an arbitrary function of impulsive angular modulation in a wide range of phase angles. The result of the processing does not depend on the random initial phase of the analyzed signal.Published
