Abstract：In this paper,the influence of system error on the accuracy of multi platform bearings only direction finding cross positioning system is analyzed quantitatively,and it is pointed out that it is one of the main factors affecting the positioning accuracy.A multi platform bearings only direction finding cross positioning system error estimation method based on kernel function mean shift(kfms)is proposed.The method uses multi-platform direction finding to estimate and fuse the target state,and then uses kernel function method to estimate the system error of each sensor.Simulation results show that compared with MLE algorithm,this method avoids matrix inversion operation,and has more stable estimation results and shorter convergence time.
