  In this paper, we propose an approach to formulate the Weapon Target
Assignment (WTA) problem with physical and seeker interference constraints
which is solvable in Mixed Integer Linear Programming (MILP). To handle the
interference constraint which is intractable in continuous time domain, we
discretize the time window and generate predicted intercept point (PIP) set.
Also, to handle interference constraints to the MILP formulation, the
interference tables that explain which pairs of assignments make interference,
are made prematurely before the solver executed. The simulation results whether
considering interference or not give different optimal solutions with different
targets show the effectiveness of our MILP formulation.
