摘　　要：现代高科技战争中,提高战机隐身性能是战机设计的重要指标之一,直接影响着战机的生存力与战斗力。飞机的雷达散射截面积是飞机隐身性能评估的重要指标之一,文中依据某型隐身飞机的公开报道信息,建立了该型战机的数字模型,采用多层快速多极子算法分析了战机在频率为10 GHz,水平极化方式与垂直极化方式,俯仰角分别为0°、5°、10°、15°、20°、25°、30°条件下,以及加了尾翼情况下的雷达散射截面积,依据分析结果,系统分析了战机减少飞机雷达隐身截面积的一些措施。In modern high-tech war,improving the stealth performance of fighter is one of the important guidelines of fighter design,which directly affects the survivability and combat effectiveness of fighter.Radar Cross Section(RCS)of aircraft is one of the important specifications for evaluating stealth performance of aircraft.In this paper,the digital model of a stealth aircraft is established based on the public report information of it.The aircraft RCS at 10 GHz frequency,horizontal polarization and vertical polarization,with pitch angles of 0°,5°,10°,15°,20°,25°and 30°respectively,and with vertical tail,are analyzed by using multilevel fast multipole algorithm.Based on the analysis results,some measures for reducing radar cross section area of aircraft are systematically analyzed.
