This paper summarizes studies of a wideband, quadrature time-integrating, acousto-optic processor designed at St. Petersburg Electrotechnical University. This processor, based on a two-dimensional quadrature, radio-frequency time-integrating acousto-optic correlator (TIAOC), offers a compact solution to detecting and analyzing wideband spread-spectrum signals for variety of radar, navigation or communication applications.


Points discussed include the overall structure of the processor, possible operating modes and corresponding post-detector processing algorithms, sensitivity, and dynamic range.
