Weather Analysis and Processing Verification for Space Debris Photometric Observations

摘要

The light curve of space debris can provide the basic target identification information. Photometric data of space target obtained by ground-based equipment are affected by weather condition, observation equipment, detector performance, etc. Among these factors, the poor weather condition during the observations could cause worst effects in the photometric data. The light curves will be smooth and regular under photometric conditions? while irregular in non-photometric nights. In addition, we can not distinguish what caused the abnormal brightness variations between weather and other factors from the traditional photometric data. Our study shows that by obtaining simultaneous light curves of background stars with an independent telescope close to the main telescope with dedicated observing tactics, we can verify the influence factors of the photometric variations in non-photometric nights.
