Abstract: This paper intends to achieve the fire-and-forget attack of the seeker/INS-less missile without relying on the real-time communication and the information of absolute positions of missiles. Two onboard strap-down finders are installed on a seeker-less missile without the Inertial Navigation System (INS) to detect the two specific targets on a seeker-guided missile. Based on these, two cooperative terminal guidance laws are derived for a stationary point target by common negative feedback and finite-time convergence approaches. Another cooperative terminal guidance law is derived for a stationary surface target by the dynamic inverse control. All the aforementioned guidance laws enable the velocity direction of the seeker/INS-less missile point to its attack target before the seeker-guided hits its target. Hereafter, the seeker/INS-less missile can fly straightly to achieve a precise hit. Simulations are conducted to verify the effectiveness and advantages of the proposed guidance laws.

Key words: missile guidance, cooperative guidance, seeker/INS-less missile, fire-and-forget attack, finite-time convergence, surface target
