摘要
从双波段红外测温的原理入手,分析了导弹防御系统EKV红外探测器对中段飞行目标的温度分辨能力,指出目标在探测器2个工作波段的发射率之比是影响探测器温度测量精度的最大因素。在假定条件下的蒙特卡罗计算表明,EKV的温度测量误差约10.8 K;当目标间的温度差别小于11.8 K时,EKV就无法分辨出哪一个目标的温度更高(均为95%的置信概率)。
Abstract：The temperature discrimination capability of the EKV IR sensor is analyzed based on the basic physics of 2-waveband infrared temperature measurement, and it is concluded that the emissivity ratio of targets on two working bands of the detector is the most significant error source statistics under typical situation shows that the temperature measurement error of the K,and when temperature difference of the targets is lower than 11.8 K, the KEV A Mont-Carlo based EKV is about 10.8 is unable to decide which object is hotter （both at confidence level of 95% ）.
