Differential Game Guidance Law Based on Adaptive Dynamic Programming for the Interception of Hypersonic Targets

With the rapid development of hypersonic vehicle technology, the research on defense approach of the hypersonic weapons is constantly deepening. A lot of guidance law researchers made their efforts to tackle with the problem of high speed, active large scale maneuverability of the hypersonic targets. In this paper, this interception problem is defined as a typical differential game, and the adaptive dynamic programming method is used to solve the Nash equilibrium solution of the nonlinear continuous time system. The numerical simulation of Matlab is provided to validate the effectiveness of the proposed guidance law. The result shows that the differential game guidance law based on adaptive dynamic programming is more robust than the baseline method, and can obtain higher interception accuracy
