An integrated design approach is described for a tactical missile which derives guidance commands from both a strapdown terminal homing seeker and a fixed-based radar system. To deal with initial errors between the fixed-based radar and missile reference systems, a separate navigation filter is designed which estimates any misalignments using the fixed-based radar measurements of the missile position and outputs of the inertial measurement unit on the missile. Simulation results indicate that small miss distances can be achieved without the need for accurate alignment of the missile prior to launch.
