Yuan Jun-chao, Xiaokuan Zhang · 2016
Based on the appearance of plasmasphere when ballistic missile enters in reentry phase at the speed of supersonic, impacts of reentry plasma parameter on the real RCS value of warhead are studied. According to the calculating method of dynamic RCS time series, the model is established to simulate electromagnetic scattering of reentry ballistic missile. By simplifying the trajectory reasonably, the model analyzes the change of RCS time series based on three classifications, different reentry ballistic, different angles of reentry and different speeds of reentry. The conclusions can be obtained through simulation that RCS time series is a kind of practical method which is fundamental for classification and identification of reentry ballistic missile warhead.
