Session 2: Associative Processors
Part of the Lecture Notes in Computer Science book series (LNCS, volume 24)


This paper describes the architecture of the Raytheon Associative/Array Processor (RAP) and its application to real-time radar signal processing. The nature of radar computations is analyzed and parallel processing requirements are characterized. The effects of these requirements upon the design of the RAP are described. Features of the operational RAP system are discussed. Finally, an implementation of a Constant False Alarm Rate (CFAR) Processor is given.
