Maneuver target interception based on multiple model adaptive estimator

A maneuver target interception algorithm based on multiple model adaptive estimator (MMAE) is researched and a modified differential game guidance law is given. The efficiency of this simplified MMAE algorithm lies mainly in the exploitation of the special structure of the evader maneuver command hypothesis space to reduce the number of MMAE elemental filters running in parallel and to realize the reduction of the computational load. To realize the reduction of the miss distance resulting from the estimation delay, the modified differential game guidance law increases the lateral acceleration command for small values of time-to-go of the pursuer to the maximum available value by enhancing the gain of the command. The Monte Carlo simulations are carried out for the homing performance comparison and the results demonstrate the superiority and effective of the proposed methods.
