To support the advanced concept technology demonstration of operational applications of multiple intelligence reconnaissance platforms on future information battlefield, multi-agent-oriented modeling technology is applied to set up the mappings from intelligence reconnaissance system's members to respective agents, by which the distributed multi-agent system is designed. In this paper, multi-agent-oriented intelligence reconnaissance system organization and agents' architecture are studied. Contract Net protocol approach is applied to the inter-agent problem, i.e., collaboration of multiple intelligence reconnaissance platform agents. The established distributed multi-agent system model shows its advantages on realizing the platform-level simulation for the external, dynamic, complex and intelligent process of intelligence reconnaissance on information battlefield.
