The utilization of functionally dedicated micro processors in radar video processing
Abstract
This paper describes a digital radar video processor, for use with 2-D search radars, that employs a functionally dedicated micro processor. A micro processor can efficiently perform many of the functions previously accomplished in either hard-wired logic or in the system central processing unit (CPU). Micro instruction execution times in the order of 150 nanoseconds enable the micro processor to perform operations previously relegated to hard-wire logic. Utilization of nonparametric rank quantizer provides a more constant first detector false alarm rate by eliminating the effects of changes in the mean value and higher order moments of the video amplitude distribution. Azimuth clutter correlation is accounted for by estimating clutter correlation and using that estimate to control the criteria for target detection, thus regulating false alarms at the target detection level.
