| Abstract: | 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. |
