Paper Abstract

A principle of the acousto-optic quadrature correlating analysis of radiosignals is discussed. Different architectures of the corresponding time-integrating acousto-optic correlators (TIAOC) have been considered, including the scheme of space-parametric TIAOC and the quadrature one with two cross laser beams. Variants of the structure scheme realization of the latter correlator, which are distinguished by quadrature channel organization method, are compared. Two-dimensional TIAOC with cross laser beams architecture is described. It has the most simple realization and can be used to analyze the crosscorrelation function of two radiosignals with the optimum values of their main parameters. The experimental results obtained from the correlator are shown to be in agreement with theory.
