Abstract
This dissertation proposes a novel integrated approach to the interception of a maneuvering target within a 3-D space. The estimator/seeker system of the intercepting missile tracks the trajectory of the target with a passive ranging law to ensure stealth capability. The passive ranging mechanism comprises a coordinate transform from Cartesian coordinates to modified spherical coordinates (MSC) as well as an extended Kalman filter (EKF) with an Interacting Multiple Model (IMM). The aim of the system is to derive accurate estimates of the target’s position, even when the target performs evasive maneuvers. Based on these estimates, the proposed guidance law incorporates second-order sliding mode control (SOSMC), such that the missile will approach the target continuously until intercepting it. Moreover, considering the practical situation in missile-target engagement, we extend one-on-one interception to multi-missile interception via multi-player pursuit-evasion (MPPE) game theory. The stability of the integrated guidance/autopilot system was and a variety of simulations were conducted to verify the efficacy of the proposed system.
