New developments in numerical modelling of the radar signature of rocket exhaust plumes

In this paper, we present the new developments of the multiphysics numerical models designed for predicting the time-dependent electromagnetic signature of rocket engine plumes. We first describe the physical and numerical model for aerothermochemical physics and for electromagnetic applications. A mock up rocket engine (MoSER) has been designed and its signature has been measured in UHF and X band. The results were compared to simulation.
