The research of guidance performance of the phased array seeker with platform for air-to-air missile

This article aims to meet a hard demand for aircraft about the Disturbance Rejection Effect (DRE) when tracks the target with great maneuver by using the phased array seeker. In order to avoid the severely constraint for seeker, the Phased Array Seeker with Platform(PASP) is put forward firstly. Then the mathematic model of PASP are established. And the feedforward compensation method is used to complete the rate decoupling. By take two methods of platform rate feedforwd into consideration, there are two basic phased array seeker with platform(PASP) seeker structure proposed. Based on that, the transfer function model of the platform phased array seeker of these two structure are established to study the design procedures and performance as well as research. Furth more, the parasitic loop in guidance loop which induced by the PASP DRE is established and the property is analyzed to used for PASP tracking loop and guidance loop design integration. And the research indicated that the PASP has a better performance than any other kinds of seeker in tracking rapidly target and can improve the guidance precision effectively.
