空间目标光度特性测量方法研究

Photometric characteristic measurement of space target

空间目标的光度特性反映了目标的在轨运动状态,通过空间目标的光度测量可以判断空间目标在轨特性和进行空间目标的编目识别。比较了空间目标光度特性光度计和CCD测量的两种方法,并采用恒星比对的方法,得到了空间目标的星等数据,实验结果表明两种测量方法星等精度相当,但CCD测量可以在白天测量空间目标的光度特性。

The photometric characteristic of space measurement, the orbit performance of space target target can reflect the movement in orbit. According to photometric is judged and the identification catalog about space target is carried out. Compared photometric characteristic measurement photometer with CCD measurement, adopted the method about star comparison, and obtained the stellar magnitude data of space target. The experimental results show that two kinds of methods on magnitude measurement have the same precision, but CCD measurement can measure the photometric characteristic of space target in the daytime.
