全天时星敏感器成像探测建模与仿真数据集

在此前的全天时恒星探测中存在信噪比低、图像质量差等问题。在此提出了视场选通新体制，并基于该新体制完成全天时星敏感器的研制，打破了视场和天光背景抑制相互制约的局限，摆脱现有方案对转动扫描机构的依赖，为全天时星敏感器技术开辟全新的技术途径，在小型化、高精度自主导航领域有着广泛的应用前景。本数据集基于全天时星敏感器原理样机产生，主要记录了全天时星敏感器探测成像建模与外场恒星探测能力仿真分析观测值，数据量1.59GB。Previous all-day stellar detection suffered from drawbacks including low signal-to-noise ratio (SNR) and poor image quality. Herein, a new field-of-view (FoV) gating system scheme is proposed, and the development of an all-day star tracker based on this new scheme is completed, breaking the limitation that the FoV and sky background suppression restrict each other, eliminating the dependence of existing solutions on rotating scanning mechanisms, and opening up a brand-new technical approach for all-day star tracker technology, which has broad application prospects in the field of miniaturized, high-precision autonomous navigation. This dataset is generated based on the prototype of the all-day star tracker, mainly recording the observation values obtained from the detection imaging modeling of the all-day star tracker and the simulation analysis of its outdoor stellar detection capability, with a total data volume of 1.59 GB.
