A new method is proposed for measuring the veiling glare index of long focal length optical systems based on the analysis of the properties and their application fields of present measurement devices and the theoretical analysis on the stray light sources is also given.
在分析现有杂光系数测量的基础上，提出了一种新的长焦距光学系统杂光系数测量的方法，并对这种方法进行了理论分
So the parameters of the signal-to-jamming ratio,clutter modulus and the detection probability can be measured in outfield.
证明了雷达信号功率比的外场可测性和收敛性,由此可在接近实战的外场干扰条件下直接获得雷达的信干比、杂波系数和发现概率等参数,这对于定量评定雷达抗干扰性能具有比较重要的意义。
