수동형 탐색기의 시선각속도 측정을 이용한 표적 접근속도 추정 Target Closing-Velocity Estimation Using LOS Rate Measurements of a Passive Seeker

Target closing-velocity is an essential information for the implementation of the proportional navigation although only LOS rate measurements are available from gyroscopically-stabilized passive infrared seekers. In most applications, target closing-velocity is empirically approximated instead of being estimated in real time.In this paper, a new estimation technique of target closing-velocity for passive homing missiles is proposed. This technique utilizes some characteristics of the proportional navigation law and only LOS rate measurements are required for the estimator. The Lyapunov method is used to analyze the stability of the estimator algorithms. Computer simulations are also conducted to investigate the effects of guidance delay and target acceleration on estimation accuracy.
