چکیده انگلیسی
Interceptor usually use direct force control to attack a rapidly maneuvering target. Thus, aircrafts should roll in response to the pulse jet engine. Furthermore, interceptors need a seeker with a simple structure and a rapid tracking rate. Phased-array strap-down seekers can be used for rolling interceptors because of their wide field of view and the absence of a stable platform. However, the disturbance from the interceptors body should be decoupled when phased-array radars are used for strap-down seekers to track rapidly maneuvering targets and thus to calculate the real line-of-sight rate. In this study, the coupling characteristics of the two channels of a spinning interceptors seeker are investigated, and a coupling model is established. The law governing the coupling process is illustrated in consideration of the interceptors motion and seeker parameters. Then, an integrated compensation method that consists of the additive rate compensation method for body disturbance, the cross-decoupling method for rolling movement, and the angle-compensation method for tracking loop dynamic lag is introduced. Finally, a simulation using the proposed method is conducted to validate its efficiency.
