Abstract:

A simple and effective terminal guidance law for exoatmospheric interceptor, which uses a kinetic kill vehicle for a direct hit kill, is proposed. Firstly, a new analytic expression of zero effort miss is derived, because the difference of gravity for interceptor and ballistic missile is taken into account, so the expression has good fidelity as compared with that in the case where gravitational accelerations acting upon both vehicles are equal. A terminal guidance law is designed using the zero effort miss steering.
