Application of reconfigurable computing in real-time electronic reconnaissance and identification system

Reconfigurable computing technology is a new computing paradigm. By this technology, resources and tasks can be assigned in joint space-time domain during different computing stages according to resource requirements. So resource utilization can be greatly improved and multipurpose application can be achieved dynamically. In this paper, we applied reconfigurable computing technology to real-time reconnaissance and identification of intensive wideband electromagnetic signals. A multiple levels dynamically reconfigurable signal processing system was designed and implemented based on hybrid architecture. We also established a Äeconfigurable Computing application Framework for the domain-specific of the intensive wideband real-time. Electromagnetic. Signals analysis and Recognition system(ESAR-RCAF) based on Model-Hew-Controller(MVC) mechanism, which ensured that the system could capture new application requirements automatically and dynamically adjust the calculation under user's intervention. ESAR-RCAF is the foundation for transforming system dynamic reconfigurable capability to multipurpose integration capability.
