| Abstract: | The system design of a space-integrating acousto-optic correlator is described,and the optical systems of single device and two devices acousto-optic signal processors are reported.Two new methods of heterodyne detection and the mathematical models of the outputs of the processor are developed.The correlation detection of the BPSK signals of the 13-bit Barker code is performed by this methods,and the experimental results that correspond with the theory are satisfactory. |
