In future parallel radar signal processing systems, with high bandwidth demands, new interconnection technlogies are needed. The same reasonig can be made for other signal processing applications, e.g., those involving multimedia. Fiber-optic networks are a promising alternative and a lot of work have been done. In this paper, a number of fiber-optic interocnnection architecutes are reviewed, especially from a radar signal processing point-of-view. Two kinds of parallel algorithm mapping are descussed: (i) a chain of pipeline-stages mapped, more or less directly, one stage per computation node and (ii) SPMD several network configurations, which are simplified due to te nature of the applications, are also proposed.
