【摘要】 介绍了在引入地球半径的理想条件下计算红外探测器最大探测距离(L)的方法。指出最大探测距离与探测器所在位置的高度以及点源目标的高度密切相关。根据探测距离的量值,可以将军用红外探测器分为3类:第Ⅰ类,探测距离L<50km;第Ⅱ类,50km≤L<500 km;第Ⅲ类,500km≤L<1500km。更多还原

【Abstract】 A method for calculating the longest detection range(L) of an infrared detector under an ideal condition is presented.The longest detection range(L) is closely related to the position of the infrared detector and the altitude of the point object source.Therefore,the military infrared detectors can be classified into three types according to their detection range values.The infrared detectors having the detection range L<50 km are classified as typeⅠ.The infrared detectors having the detection range 50 km≤L<500 km are classified as typeⅡ.The infrared detectors having the detection range 500 km≤L<1500 km are classified as typeⅢ.更多还原
