Analysis of a new cooperative guidance law for improved target tracking by multiple UAVs

In this paper, a new feedback cooperative guidance law(CGL) for target estimation developed in a previous study is introduced, which is derived using only one-step Fisher Information Matrix(FIM) to quantify the amount of target information through an indirect optimal approach. In fact, however, because FIM is based upon true target states, if estimated states are applied to the CGL, it is possible to generate a difference from an ideal command. Therefore, this paper investigates sensitivity of resultant command in terms of target estimation error analytically and it is proved by conducting closed loop numerical simulations.
