Researching Digital Methods of Generation Signals of Hydroacoustic Phased Antenna GridsЖурнала ТУЗС - Том 7, №1, 2021

  • Abstract: Solving tasks of creation, correction and parametric control of signals excitation hydroacoustic phased antenna grids is actual problem of creating multichannel generated devices, based on switch-mode amplifiers with pulse-width modulation. In this article were reviewed correction methods output signals of hydroacoustic transmission paths, periodic pulse sequence creation and parametric voltage level control of excitation channels of phased antenna grid with abrupt decrease impedance of hydroacoustic converters. Was shown the perspective implementation digital technologies for improvement parameters modes of hydrolocation with deterministic library of signals. Presented digital control methods of output signals in hydroacoustic transmission paths are characterized by scientific novelty and originality of the proposed technical decisions.
  • Keywords: multichannel generator device, switched amplifier, pulse-width modulation, hydroacoustic transmission path, hydrolocation, digital control methods.
