The adaptive weighted data fusion algorithm is used to calculate the weighted values in real time using the measured data and the measured data are fused using the weighted values to obtain the state estimation of the target.The algorithm fully reflects the real-time changes of the measured data and realizes the optimal weighting factors Dynamic in-line adjustment, the error variance of the fusion result is less than the variance of the measurement error of any single measurement equipment.This method adopts recursive calculation, has a small amount of calculation, has good rapidity, is suitable for real-time calculation applications, Real-time decision-making to provide accurate and reliable basis to better meet the actual needs of the project.
