A composite guidance for dual range AAM with side jet control

The dual range air-to-air missile (DRAAM) is a next-generation AAM concept capable of all-aspect target intercept at very close range, as well as beyond visual range (BVR). A composite guidance strategy for DRAAM with initial side jet control (SJC) is synthesized in this study. The initial side jet thrusters integrated into the aft section of the rocket motor are used when high levels of agility are required to engage such as over-the-shoulder engagement. For this short range all-aspect engagement, a sliding mode agile turn guidance law in the yaw plane is invoked to perform the high-angle-of-attack maneuver in 2.5 seconds. On the other hand, for the beyond visual range (BVR) engagement, a simplified version of singular perturbation (SP) optimal midcourse guidance law based on the composite control approach is proposed. During the homing phase, a composite homing guidance strategy is presented. A traditional PN guidance law is utilized first, and then a bounded differential game (BDG) homing guidance law with aero control is proposed in this study for the purpose of hit-to-kill end game performance.
