In this paper, a new cooperative guidance law (CGL) which maximizes a target information without computation load is introduced. The CGL is very practical in real-time operation since its command could generate a command to avoid a risk-zone and has a simply decentralized command structure. Since the CGL is derived through an optimal method using each one-step target information from N UAVs, it proposes a sub-optimal heading command to maximize target information. So, once some target information from close agents is shared, the CGL can generate each heading command indepently. Generally, Kalman Filter (KF) is considered for data fusion after the information sharing, but the algorithm is centralized so calculation burden is not light and this structure is not proper to handle multiple independent UAVs. For more perpectly decentralized overall architecture, therefore, decentralized extended information filter (DEIF) is applied to the guidance law.
