红外探测设备抗阳光和海面亮带干扰试验设计

Test Design of Infrared Detector Anti-jamming of Shine and Sea Surface Shine

红外探测设备抗阳光和海面亮带的干扰能力是其抗干扰能力的重要部分。为科学有效地检验该能力,对该试验设计的关键问题开展分析和研究。首先根据天体运动规律,分析了获得太阳高度角和方位角流程,然后研究了飞行航路设计原则,推导了试验中航路有效区间模型,建立了检飞航次数的数学模型,最后通过仿真算例证明了该方法的合理和有效。

Anti-jamming of shine and sea surface shine capability of infrared detector is an important part of anti-jamming capability.To effective test,the key-problem is analyzed and studied.Firstly based on celestial bodies movement orderliness,it is analyzed to obtain the sun elevation and azimuth process.Then,the principle of air route design is researched.The effective interval model of the flight path in the experiment is deduced,and the mathematical model of the number of flight inspections is established.Finally,the rationality and validity of the method is demonstrated by emulation example.
