Simulation of aircraft trajectory and radar echo signals
In order to accurately simulate the dynamic response of an aircraft,a radar echo signal simu lation model was developed for deeper analyses of the dynamic characteristics of a single vehicle in a fault state.Firstly,the model integrated the center frequency of the radar with the signal sampling frequency,and successfully detected the complex three-dimensional flight trajectories of the vehicle under different altitude and speed conditions.Secondly,the model accurately simulated the nonlinear Yaw jitter phenomenon after the fault of the vehicle and its significant effect on the flight trajectory.Finally,the simulation results were visualized by 3D trajectory diagrams,signal diagrams in time and frequency domains,and altitude change diagrams,which not only verify the accuracy of the model,but also enhance the analysis of target detection capability under different flight conditions.This physical simulation method provides a reference for the monitoring and response of radar systems un-der complex conditions.
