A Novel Penetration-evade Guidance Law against Two Homing Missiles

[摘要] A novel guidance for an evader which is exposed to a threat of two homing missiles is presented. Each missile is assumed to measure solely its own line-of-sight (LOS) angle and share it with other missile. Such information sharing enables the missiles to form a triangular measuring baseline relative to the evader and to improve their estimation accuracy. However, if the separation angle between the two LOS is small enough, the observability of such double-LOS measuring approach becomes weak. Motived by this observation, the idea of the proposed concept is to bring the missile on the same LOS with target in the first stage. As for the second stage, the evader perform an appropriately timed maximum evasive maneuver. The simulation results demonstrate that the proposed guidance law can reduce the estimate and guidance accuracy of interceptors and achieve the goal of penetration.
