Abstract

Abstract: The common coordinate systems, such as earth-centered earth-fixed, navigation, airframe and line of sight coordinate systems, are introduced, and the homogeneous transformation between them is summarized to analyze the influence of forward motion on the scanning strtegies of electro-optical stabilized sighting system. The imaging mechanism of two-axis 4-framework stablized sighting system during the forward motion of aerial carrier is discussed using kinematic expression from the perspective of differntial kinematics. A full-link simulation model is proposed for the internal control components in the sighting system and the geographical orientation. A control action is applied to eliminate the influence of forward motion on the sighting system in the proposed model. The positioning and scanning processes of the sighting sysytem in the air were simulated by introducing the electronic and kinematic parameters in the proposed model. Simulated results show that the theorectical analysis of forward motion is correct and effective, the full-link simulation model is available.
