Abstract
The systems design of a real-time hybrid digital-optical correlator is deta iled. Emphasis is on: partitioning of the digital and optical systems such that the efficiency of the optical image train is maximised; and the parall elisation of tasks within the digital sub-system to maximise throughput. Th e significance of communication bottlenecks are emphasised in the digital s ystem and the constraints this enforces on the initial selection of DSP dev ices. (C) 1999 Elsevier Science B.V.
