航天器微流星体及空间碎片防护结构性能分析

Most of the spacecrafts are suffering from the bad space environment, and the space debris, included meteoroid and orbital debris, imperiled the spacecrafts most.

其中对航天器威胁最大的就是空间碎片,包括微流星体和轨道碎片。

Star volume is a contemporary stereological parameter reflecting the (mean) local size of an arbitrary structure (especially an irregular structure), and can be unbiasedly estimated by measuring the point-sampled intercepts.

星体积是反映任意结构（尤其是不规则结构）的（平均）局部大小的体视学新参数，可据点取截距测量进行无偏估计。

On the process of star identification,the tradition al-gorithm is improved and a suitable alogrithm of pixel labeled in binary image for star image is presented.

在星体识别过程中对传统算法进行了改进,提出了一种适合星图的二值图象标记算法,对星体进行了有效识别。
