典型隐身飞机动态RCS时间序列研究
Analysis of Dynamic RCS Time Series of Typical Stealth Aircraft
摘要
Abstract
The inter-coordinate transformation relation between target body coordinate and ground-based radar coordinate is defined and derived,the azimuth and the elevation of line of the sight of radar in target body coordinate are obtained in this paper.All-airspace static RCS value can be available by establishing typical stealth aircraft models,including F-22,in software FEKO and the RCS characteristic variation of the dynamic target is simulated and analyzed by using Matlab.The simulation results show that different altitudes and route shortcuts all can influence the RCS series of maneuver target,and the RCS value is lower when the target takes some proper pitch movement.Also the simulation can provide a foundation for the design of flight track for stealth aircraft in simulating active attack.关键词
