With regarding to the midcourse interception strategy with terminal impact angle constraint that the air-breathing hypersonic vehicles encounter during the cruise phase, the mathematical model of attack and defense countermeasure is established on the basis of the appropriate hypothesis on bilateral strategies and then with specified bilateral terminal trajectory angle errors as terminal constraint, maximum terminal vertical and horizontal position errors and minimum control inputs as performance index, a penetration trajectory satisfying control inputs’ saturation limitations is developed with optimized Model Predictive Static Programming(MPSP). Furthermore, by the optimized algorithm, not only the convergence rate is guaranteed under the vehicle’s control inputs’ saturation limitations, but the convergence robustness is enhanced under different initial conditions and constraints by adaptively adjusting the weight matrices of control inputs and the vector errors between expected and actual terminal states.
