Optimized automatic target recognition algorithm on scalable Myrinet/field programmable array nodes

Automatic target recognition (ATR) in synthetic aperture radar (SAR) imagery often requires billions of operations per second. This paper describes a compact scalable system developed at Myricom for high-performance implementation of the template-based SAR ATR algorithms developed by Sandia National Laboratories. The Myricom system is mapped on the multiple concurrent field programmable array (FPGA) computing nodes connected by Myrinet. These FPGA nodes achieve high efficiency, through the exploitation of the unique characteristics of the ATR algorithm in FPGA. The contributions of this paper are the descriptions of the architectural designs for the ATR system on the scalable FPGA nodes.
