A semi-physical simulation platform is constructed,including a multi-stage carrier rocket simulation data generator,a digital echo generator,an analog target tracking system,and an accu-racy evaluation system through studying the entire flight process of multi-stage carrier rockets.The multi-model selection algorithm is used based on the IMM framework for simulation tracking experiments,obtaining a set of matching parameters.Furthermore,actual measured data are input into the semi-physical simulation platform to validate the algorithm.The simulation results indicate that the multi-model selection algorithm based on the IMM framework features high robustness and lag-free tracking,and is suitable for practical engineering applications.
