Abstract:

This thesis examined the correlation between selected parameters characteristic of an infrared-guided ant-satellite attack against a geosynchronous target. The countermeasure employed was a balloon decoy. The criteria used to evaluate the parameters was the balloon-to-target ratio, measured at the output of a seeker detector. Specific design of the seeker detector, ASAT weapon and the balloon decoy were not addressed in this study. Coplanar orbits were assumed for all vehicles, with the target intercept point coincidental with the ASAT orbits apogee. The ASAT endgame was modeled and implemented on a digital computer. Decoy parameters investigated were the weapon-target range at time of decoy ejection, the the magnitude and direction of the balloon velocity at ejection. The field of view of the seeker was also considered. Results indicated a minimum balloon-to-target ratio needed, corresponding to selected nominal values of remaining parameters, to decoy the ASAT weapon. Keywords Infrared decoys Theses.
