【摘要】 从辐射传输理论出发,计算分析了目标特性对0.4-14μm波段范围内的目标背景对比度的影响,计算结果显示,在其他条件不变的情况下:1)随着目标物固有亮度的增加,目标背景对比度增加,而且其谱分布也发生相应的变化,紫外与可见光区的对比度增加幅度大于红外区的增加幅度;2)目标物固有亮度的谱分布影响着目标背景对比度的谱分布;3)随着目标物表面反射率的增加,目标背景对比度的值也增加,并且目标物表面反射率的谱分布也影响营目标背景对比度的谱分布。更多还原

【Abstract】 The problem about target discretion is very important in many space applications. It was obtained that the relation between the natural radiance of targets and the target-background contrast at 0.4-14 μm. And detailed research about the effects of the radiance and the reflection of the target was also carried out. As the result, the contrast is increasing with the radiance and the reflection increase. And the spectral radiance and the spectral reflectivity affect the spectral distribution of the contrast.更多还原
