Space debris detection methods utilizing hyperspectral sequence analysis based on Hilbert-Huang transformation

Detection is the prerequisite and basis for the control of space debris distribution, as well as a critical work about the observation and study of space debris. The proposed method uses hyperspectral imager for space-based sampling, which can detect the weak differentiation caused by the rotation of target. It also overcomes this trouble that space-based visible light camera cannot take advantage of the fact that space debris makes a rotate motion around its spindle to detect. Therefore, the decision for space debris can be based on object's special motional information without any sampling images of space debris. Further details in spectral signal can improve the detectability of target, especially for pixel-level dangerous space debris objective is to bring the double-break in detection method and accuracy.
