大气数据传感器对飞行器隐身性能影响分析

Analysis of Air Data Sensor on Stealth Performance Affects for Aircraft

大气数据传感器是影响飞行器飞行安全及武器精确打击的重要飞行传感器。根据雷达频段的分布特点,利用电磁场分析软件FEKO,仿真分析了外露于飞行器表面的大气数据传感器及与飞行器表面齐平安装的嵌入式大气数据传感器在水平极化方式和垂直极化方式下对飞行器雷达散射截面积的影响;定量分析了探测器工作波段、嵌入式大气数据传感器表面温度及表面积对红外辐射度及飞行器红外隐身性能的影响。总结了降低大气数据传感器对飞行器隐身性能影响的方法。

Air Data Sensor is an important flight sensor which will affect aircraft flight safety and weapon precision.This paper according characteristics of distribution of radar frequency band has analyzed effects of air data sensor on exposed surface and flush air data sensor which is flush-mounted on aircraft surface on Radar Cross Section( RCS)of aircraft by using electromagnetic field analysis software FEKO at the modal of vertical polarization and parallel polarization. And this paper has quantitatively analyzed effects of the working wavelength of the detector,the surface temperature and surface area of the embedded air data sensor on the infrared radiation and the infrared stealth performance of the aircraft. Summarized methods that will reduce effects of air data sensor on stealth performance of aircraft.
