Abstract

Based on the analyze of the infrared object detection mechanism, a new physical quantifier --detectability, which is used to describe how difficult it is to detect an object, has been defined. The change of flying velocity influence the radiation characteristic; the change of flying altitude also influence the radiation characteristic of the object ,the radiation characteristic of atmosphere background, the most effect view of detector for the object, atmospheric transmittance of the path and so on. Based on the large number of calculation, the article analyses the rule of the influence and change, the influence that the flying altitude and velocity to infrared band detectability. The analyzing result show that when the flying velocity of target enhances 0.5 Mach, the work range will enhance 5 kilometers for the same infrared detector. The detectability of an object will increase as the flying altitude increasing until reach the 8 kilometers; at the altitude of 8 to 10 kilometers the detectability reaches the max, when the altitude overrun 10km the detectability of an object will reduce as the altitude increase.
