| 摘 要： | 本文设计并完成了银河背景下碎片探测试验，数据分析表明，强的银河背景会降低探测器对暗弱碎片的探测能力，但对碎片的天文定位精度影响不大。本文验证了采用基于探测概率的极限探测星等方法表征探测器极限探测能力的合理性，以及基于仿真的方法增加数据完备度的可行性。本文的工作将为后续天基探测器的设计及探测试验的开展提供依据。

| Abstract: | We design and complete an experiment of debris detection under the Milky Way background. The data analysis shows that the strong Milky Way background reduces the detector’s ability to detect the weak debris, but has little effect on the accuracy of the astronomical positioning of debris. This paper verifies the rationality of using the limit detection magnitude method based on the detection probability to characterize the limit detection ability of detectors. It also verifies the feasibility of using the simulation method to increase the data completeness. The work in this paper will provide a basis for the design of the space-based detectors and the development of the detection experiments. |
