INVESTIGATION OF ACOUSTO-OPTIC PROCESSOR FOR CORRELATIVE AND SPECTRAL ANALYSIS OF MICROWAVE RADIO SIGNALS

The investigation object is the acousto-optic processor for correlative and spectral analysis of the microwave radio signals including the two-dimensional quadrature acousto-optic correlator with time integration (AOCTI) and device for after-detector processing of the signals on base of the personal computer. The new algorithm for two-channel detection of the random signal using the specific features of the signal processing in the two-dimensionsal quadrature radio-freqiency AOCTI has been proposed. The design of the dynamic range in the two-dmensional AOCTI taking both the external noise and hardware noises of the device into consideration has been performed firstly. The developed methods for optimization of the device parameters for a purpose of achieving maximal dynamic range are new also. The analysis of influencing premediated interferences on the characteristics of the two-dimensional quadrature AOCTI has been performed firstly. A possibility to perform the acousto-optic quadrature correlative processing in microwave range has been confirmed in experiment firstly. The basic results of the investigations can be used at development of the perspective acousto-optic processors intended for processing of the bandwidth radio signals both of the determinated and random character in the radiotechnical systems of different purposeAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
