Analysis of the Impact of Aircraft Movement Feature on Dynamic RCS Series

To solve F-22 the problem of difficult at detection for supersonic feature speed stealth target,the the dynamic research tracks RCS on of and stealth aircraft different response movement is simulated and further the frequency and polarization angles characteristics with is done are in this paper.The flight are set the real-time and of radar sight random jitter obtained.of Subsequently,by using physical optics tracks method simulated of equivalent and currents,the dynamic movement RCS different that speed the aircraft at different on flight is analyzed.RCS As for the feature has biggest effect the dynamic RCS,its dynamic show on different affects frequencies dynamic and polarizations is simulated.The simulation and results RCS that lowest the flying speed RCS course differently short-cut can at at different lower flight higher tricks,speed.the value is when the aircraft flies at small or By using the frequency this and are polarization of response characteristics weaken and the influence efficiently.The results of paper great significance to the early warning detection of supersonic speed stealth aircraft.
