Research on the Method of Simulation Flight Path Gen-eration for Virtual Firing Test of Air Defense Equipment
The virtual firing test of ground-air defense equipment is a new mode of range test of"vir-tual flight and actual combat",which can effectively reduce test costs,shorten test cycles,and provide a new method to test equipment boundary performance.However,the simulation flight path generation of virtual target drone aircraft is one of the difficulties.A flight path generation method is proposed by the superposition of the target motion equation and the radar measurement error model.The radar measure-ment error model is constructed with multiple linear regressive analysis and least square method,the prob-lem of calculating radar measurement errors is solved under corresponding states based on historical experimental data.Finally,historical experimental data are selected for verification and analysis,and a corresponding radar measurement error model is established.Then the data of simulation flight path are obtained by superposition of the complex tactical maneuvering actions of a single aircraft.The analysis results indicate that the root mean square errors of the elevation angles measured values and azimuth angles measured values in the generated flight path according to the method are 0.110 mils and 0.166 mils,and the root mean square error of the distance measured value is 2.285 meters,the experimental requirements can be met.
