Abstract :
The terminal guidance problem for the interception of hypersonic maneuvering targets in a stochastic environment is studied. A novel logic based switching differential game guidance law named DGL/S, integrated with advanced multiple model filtering algorithm named Fast UKF/MMAE for nonlinear system, is developed. Simulation results show fast UKF/MMAE has higher estimation accuracy and shorter convergence time after the identification of target maneuvering than the common UKF/SF method, thus when fast UKF/MMAE filters were integrated to the novel guidance law DGL/S regarding of compensation of filtering delay, better homing performance is obtained.
