Simulation Analysis of Tracking and Control Link Level in Launch Vehicle Based on STK

The target feature analysis is essential for sea based launch vehicle tracking and control. The analysis method is performed with recognizing gain changes of telemetry antenna pattern in task usually and computing the automatic gain control (AGC) signal received by TT &C station manually. Aiming at the problems of low efficiency, complicated process and human errors, the method is discussed for a simulation analysis of tracking and control link level in launch vehicle based on STK, which elaborated emphatically for generating the electromagnetic field radiation pattern accord with STK format by launch vehicle antenna pattern. Compare the results of simulation and actual tracking by the launch vehicle in a flying, it indicates that the proposed method can satisfy the requirement in task and the result of simulation can be the reference by target feature analysis on launch vehicle.
