The hypersonic target detection and recognition sys-tem is studied,on the basis of overall planning and design,a multi-agent system (MAS) structure and intelligent+ information processing mechanism based on target detection and recogni-tion are proposed,and the multi-agent operation process is ana-lyzed and designed in detail.In the specific agents construction,the information fusion technology is introduced to defining the embedded agents and their interrelations in the system struc-ture,and the intelligent processing ability of complex and uncer-tain problems is emphatically analyzed from the aspects of auto-nomy and collaboration.The aim is to optimize the information pro-cessing strategy of the hypersonic target detection and recogniti-on system and improve the robustness and rapidity of the system.
