ABSTRACT:
A wide dynamic range digital receiver for radar or sonar applications wherein the wide dynamic range is achieved by increasing the sampling rate of the received signals through the use of a special purpose microprogrammed digital receiver processor implemented with a plurality of processing elements especially designed for performing sum of products' computations on a pipelined basis. The processing elements utilize VHSIC technology to achieve multiplication of two 24-bit operands at nanosecond rates.
