【摘要】 本文介绍了一种新型校飞靶标研制工作中表面对比度的测量以及与测量相关的调制度的计算方法。讨论分析了靶标表面两种测量方式的结果,还着重讨论了与测量相关的两种调制度的计算方法,将1931CIE—XYZ系统的明度值引入调制度的计算,提出了分波段计算调制度的观点。研制的靶标经实际使用,很好的满足了要求。更多还原

【Abstract】 In this paper We describe the technique how to measure the contast and calculate the modulation related to the measurement for developing a new type of flying test target. The results from the two different way to measure the surface of target are analyzed, in addition. The two kinds of method for calculating modulation related to the selected way of measurement are deeply discussed. When the lightness of 1931 CIE -XYZ is introduced in calculating modulation, a concept of calculating the modulation of selected ordinate method is put forward. The target developed in the way, has been successfully applied in practise.更多还原
