Precision inertial navigation system aiding for terminal radar seeker application

Abstract

The characteristic of Inertial Navigation System (INS) is discussed roundly at the outset, specially the potential application of information on the precision INS (PINS) in terminal guidance. Based on the gimbaled and strapdown inertial navigation system working principles, the output information of INS and PINS is compared, and the information fusion feasibility of Active radar seeker (ARS) and PINS is elaborated. This paper discussed the application of PINS/ARS fusion information in target-acquisition to enhance the acquisition performance and in terminal guidance to enhancing anti-interference performance. Simulation experiment results and theory analysis proves the validity of the method. (4 pages)
