In this paper we describe two new hybrid time and space integrating acoustooptic correlators and their use in spread spectrum applications. These systems employ 1-D or 2-D masks and are of use for many spread spectrum coding schemes and very long codes. Synchronization and demodulation of very long codes are achieved in these systems with an infinite range delay search and with nearly the full processing gain of the code. A statistical analysis of coherent and partially coherent output time integration is included (this appears to be most appropriate for any hybrid processor) together with initial simulation results.
