ABSTRACT

The performance and the salient operation features of an interference correlator with a modified optical twin-wave Rayleigh interferometer system in the mode of measurements of phase shifts between radar signals are considered. Such measurements for signals received from two antennas provide information on the angular position of an object or its displacement. A system wherein radio signals are fed for processing into a correlator with the aid of a double acoustooptical cell with a paratellurite acoustic line is experimentally realized and investigated. We consider the modes of system operation when a signal is generated in the regions of the extrema of the correlation functions and in the regions of their strongest variation (extrema of the derivatives). The accuracy of measurements obtained experimentally for the phase shifts between radio signals reaches 0.003 rad to give an accuracy of determining the signal time delays of the order of 0.005 ns in the frequency region of 100 MHz.
