22 April 2009 Gimbal stability requirements for target image enhancement
Author Affiliations +
The new Target Scene Projectors (TSP) mounted to moving gimbals require a high degree of gimbal stability to prevent image blur. Higher accuracy seeker systems require a stable target scene to follow a kinetic impact scenario. A tradeoff exists between stiff, heavy gimbals and travel dynamics. High gimbal dynamics require light, low inertia gimbals and small, simple target projectors. With the lighter and smaller Target Scene Projectors, the tradeoff allows both stiff gimbals and robust dynamics with high lineof- sight accuracies. This paper compares the gimbal-pointing accuracy to the pixel cluster size of current Target Scene Projectors. This allows higher accuracy seekers to remain on target during the highly dynamic terminal phase of a mission scenario.
