Abstract :
This paper presents the RF link prediction results for tracking system of KSLV(Korea space launch vehicle)-I especially, these are compared in terms of both the feeding methods of two onboard antennas and the antenna polarization of ground radar. According to dynamic link results considering the trajectory and attitude of launcher, onboard switching technique and radar circular polarization improve link stability and margin, and furthermore increase maximum tracking range.
