Passive Cooperative Location Based on Weighted Nonlinear Least Squares
LI Siqi
Abstract：For sensor precisions are different for multi-sensor fusion location,a passive cooperative location method based on weighted nonlinear least squares is proposed.The loss function of weighted error squares sum,based on the relation between sensor measurement and target position,is constructed.And then,the optimized criterion of Gauss Newton descent is utilized to iteratively solve the loss function.While it is less than checking static value,the final position information of target is gotten.Simulation results show that the method can make use of different covariance measurement to process and attain high precision target location value.
