Analysis of the influence of dynamic characteristics on single station dynamic radar cross section
At present,there are fewer studies on dynamic modeling in dynamic RCS simulation,the target aircraft parameters cannot be obtained,and the accuracy of simulation results from the com-monly used simplified dynamic model cannot be guaranteed.Taking the dynamic RCS of a typical trajectory as the research object,the dynamic model is established on the basis of the full 6DOF model and the simplified 3DOF model under the simulation of a trajectory,and the dynamic online joint simulation is used to obtain the dynamic RCS data under a typical trajectory through statistical analysis and correlation analysis.The dynamic RCS data of the aircraft under typical flight paths are obtained,and the differences in the dynamic RCS corresponding to the two dynamic models are com-pared and analysed by statistical analysis and correlation analysis.The simulation results show that in the manoeuvring flight phase,the attitude angle changes lead to the RCS error,but from the per-spective of the whole flight process of the flight path,under different flight speeds and different radar detection bands,the RCS trends under two dynamics models are basically the same,which show ex-tremely strong correlation,and the 3DOF simulation model is basically able to satisfy the require-ments for the modelling of the dynamic RCS characteristics in the course of the flight path.
