Abstract

Seeker filter is an important subsystem in modern homing guidance system of advanced13; intercepting missiles. Seeker filter design for homing guidance requirements are highly demanding and13; challenging. Very low filter lag, high noise attenuation are some of the challenges that need to be addressed.13; This paper presents an interacting multiple model augmented extended Kalman filter (IMM-AEKF) design to13; operate as seeker filter in close loop homing guidance of an interceptor to track evasive targets. The13; performance of the seeker filter is verified with six degree of freedom interceptor-target engagement simulation13; with seeker filter in guidance loop of the interceptor. Different filter performance criteria have been used to13; verify the performance of the seeker filter. The seeker filter efficiently handles the various seeker noises and13; provides a smooth estimate of target states to generate guidance command for intercepting missile. The miss13; distance achieved is within the acceptable limits.
