摘要
仿真分析了超音速隐身飞机的飞行速度对其动态RCS序列及雷达检测性能的影响。首先依据空气动力学原理设定飞行航迹,并考虑实际中随机抖动的影响,获取时变雷达视线姿态角;然后应用物理光学并结合等效电磁流的方法,仿真分析了飞行速度对动态RCS序列的影响;最后基于隐身飞机RCS起伏数据,推导出起伏目标检测概率计算公式,进一步研究了速度对雷达检测性能的影响,得出飞行速度越高,发现概率越低且起伏越剧烈的结论。研究成果可为超音速隐身目标的探测提供依据。
This paper analyzes an influence of speed of the supersonic speed stealth aircraft on dynamic RCS series and radar detection performance.First of all,the paper sets flight tracks in accordance with aerodynamics,and obtains the real-time angles of radar sight with random jitter.Afterwards,the paper analyzes an influence of speed on dynamic RCS series by utilizing physical optics and method of equivalent currents.Finally,based on the stealth aircraft's RCS fluctuating data,the paper deduces the computational formula of detection probability of fluctuating targets,and researches on an influence of speed on radar detection performance.The results show that the greater the speed is,the lower is the probability,and the more severe is the fluctuating detection.This research can provide a support for the detection of supersonic speed stealth target.
