Multi-sensor management can be described as a process that provides automatic or semi-automatic control of a
suite of sensors or measurement devices, which can improve the whole performance and gives an effective usage of resources. This paper presents a general model of multi-sensor allocation, and a study of multi-sensor allocation based on modified Riccati equation and Kuhn-Munkres algorithm is provided. And the steps of solving optimization are given. Simulation results show the feasibility of this method.
