目标红外波段辐射亮度差通用计算方法

Universal Calculation Method for the Target Radiation Brightness Difference in the IR Band

在采用NETD计算红外热像仪的探测距离时,需要计算目标在热像仪探测波段范围内的辐射亮度差。提出了一种红外波段目标的辐射亮度差通用计算方法,可提高利用NETD计算热像仪作用距离的准确度。

When the detection range of the IR thermal imager is calculated by using NETD, the target radiation brightness difference must be calculated in the operating wave band. A universal method for calculating the radiation brightness difference of the target in IR band is proposed. It improves the accuracy of the operating range for the IR thermal imager by using NETD.
