Guidance and ignition control of lateral-jet-controlled interceptor missiles

The guidance and ignition control strategies of lateral-jet-controlled interceptor missiles are proposed based on capture region. The system states keeping inside the capture region will lead to a successful interception. The designs of the non-ignition region enhance the robustness to cope with maneuvering targets. Then, the new ignition control strategies are presented based on dealing with the limitations of the missile dynamic time, the measurement noise, and the shrinking rate of non-ignition region. It is shown that the lateral jet with the fixed acceleration consumes a little more fuel than that with continuously variable accelerations. The main method consumes less fuel than the simple method because of the variable k and the non-ignition region. The results also reveal that the lateral jet can cope with target maneuvering.
