Abstract
Exoatmospheric IR detector is an effective means of space debris detection. In order to achieve the goal of an effective detection for low-orbit space debris, study the detection range for exoatmospheric IR detector. Studied the infrared detection technology, as well as the specific characteristics of the low-orbit space debris and other related aspects. First of all, introduce the method of detection process and determine the characteristic parameters of the space debris and infrared detectors. Then, calculate the space debris’ own infrared radiation energy and the background radiation energy. Then, by the infrared detector receives the photon number, refer to the engineering practice, the detecting range for exoatmospheric IR detector enhanced in evidence. The ground-based experiment demonstrates the calculation is preciseness and credibility. The space debris’ orbital height is 550KM and its size is 8m × 1.2m × 0.025m. Under such conditions, the detecting range for exoatmospheric IR detector is 48KM .This method can provide a certain referential significance for pace debris detection, imaging, and attacks.
