Abstract：The deployment of multiple sensors has a direct effect on the multi-sensor passive location, and a proper trajectory of a moving observer can evidently improve its passive location accuracy.Dynamic deployment of multi-flight formation can boil down to deployment of multiple sensors and optimization of flight heading.It can be translated into nonlinear programming by the determinant of Fisher information matrix criterion, with scatter search method applied to find the global optimal solution.What's more, how to choose the optimal trajectory of the formation and how long to re-deploy the formation are discussed and some valuable conclusions are drew.Simulation results show that the optimization algorithm of dynamic deployment proposed in this paper visibly improves the accuracy of multi-flight formation passive location, making it meaningful in the engineering.
