Abstract：Aiming at the problem of poor survivability of helicopters facing advanced infrared guided missiles and the jamming efectiveness evaluation method can not meet the evaluation needs in the current battlefield environment，effect evaluation criteria of new system combined surface source interference is proposed. Based on this criterion，a model of MANPADS movement，seeker tracking model，new system combined surface source interference motion difusion modeland interference performance evaluation model are constructed. The jamming efectiveness in the helicopter penetration scenario is simulated，and the survival probability of helicopter in diferent attack positions and distances is evaluated.A reference for evaluating the efectiveness of jamming bombs and improving the survivability of helicopters in the battlefield is provided.

Key words： helicopter；combined surface source interference；effectiveness evaluation criteria; survival probability
