The High Altitude Detection of Astronomical Radiation (HADAR) is a novel wide-field Cherenkov Telescope. It is designed for gamma-ray astronomy in the energy range of 10 GeV to 100 TeV, with gamma-ray bursts (GRBs) being one of its primary research focuses. To assess its complementary capabilities, this study first presents the Crab sensitivity of HADAR. Then, to compare the sensitivity of GRBs, the observation time for all experiments is standardized to 100 s. To clearly demonstrate HADAR’s advantages, we estimate its observational results with a 221009A-like GRB. The study found that HADAR is capable of more comprehensively recording the bending and absorption of self-Compton radiation, which is expected to fill observational gaps in space- and ground-based experiments. We anticipate that this facility will ensure a large statistical GRB sample and advance our understanding of GRBs.

HADAR项目伽马射线暴观测灵敏度研究


高空天文辐射探测（HADAR）是一种新型的宽视场切伦科夫望远镜。它专为 10 GeV 至 100 TeV 能量范围的伽马射线天文学而设计，其中伽马射线暴 (GRB) 是其主要研究重点之一。为了评估其互补能力，本研究首先介绍了 HADAR 的 Crab 敏感性。然后，为了比较GRB的敏感性，所有实验的观测时间被标准化为100秒。为了清楚地展示HADAR的优势，我们用类221009A伽玛暴来估计其观测结果。研究发现，HADAR能够更全面地记录自康普顿辐射的弯曲和吸收，有望填补天基和地基实验的观测空白。我们预计该设施将确保获得大量伽马暴统计样本，并增进我们对伽马暴的了解。
