Yu Zhe Wang, Juan Wang, Hang Su, Min Wang · Applied Mechanics and Materials · 2014
In order to meet the requirements of target tracking problem in terminal guidance of intercepting an aircraft, based on Gaussian-Newton Iteration strategy, a novel divided differential filter was introduced, which guaranteed higher estimation accuracy than the commonly used EKF and UKF methods. The relative small computation load made it possible for real time implantation of the filter and simulations based on a typical terminal guidance model proved the correctness and effectiveness of the proposed filter.
