A Fast Simulation Algorithm for Calculating the Allowable Attack Area for Air-to-Air Missiles

Three degree or six degree simulation algorithm can attain high precision in calculating the allowable attack area of air to air missile. But it is too complicated to meet the real time requirement in application. We propose a fast simulation algorithm to solve this problem. Section l gives the fast simulation algorithm, and the mathematical model used in the algorithm. By simplifying the model of missile, and improving computation methods, we greatly reduce the computation overhead while maintaining acceptable precision. Section 2 gives the simulation results. The table in Section 3 gives the computation time of the abovementioned three algorithms. Simulation results show that our algorithm can meet the requirement of real time application, as well as precision.
