Nowadays, air defense systems can be considered as the most integral defense equip- ments. This study has focused on two major challenges in these systems, namely, guidance law and guidance lter design. In this regard, two case of utilizing measure- ments of an on-board seeker mechanism and also a ground tracker measurements are studied. In case of utilizing ground tracker measurements, a novel command to line of sight (CLOS) law is suggested taking the advantages of nested saturated feedback (NSF) strategy and a cubature Kalman lter (CKF). Expressing problem in pursuer's LOS frame and utilizing estimated variables provided by target lter, new feed-forward terms are proposed which are exact...
