The High Altitude Detection of Astronomical Radiation (HADAR) experiment is a refracting terrestrial telescope array based on the atmospheric Cherenkov imaging technique. It is a hybrid array consisting of four water-lens telescopes and a surrounding scintillation detector array for observing Cherenkov light induced by cosmic rays and gamma rays in the atmosphere from 10 GeV to 10 TeV . The HADAR experiment possesses the advantages of a large field-of-view and low energy threshold, so it can continuously scan large sky area and easily observe the galactic and extragalactic gamma-ray sources. In this study, we will present the prospects of using the HADAR experiment for the sky survey of gamma-ray sources based on Fermi-LAT sources, and provides a one-year operation of statistical significance. Through simulated analyses of these sources, it is anticipated that HADAR will detect a total of 93 gamma-ray sources with a significance exceeding 5 standard deviations during one year of operation. These sources comprise 45 galactic sources, 39 extragalactic sources, 3 sources of unknown type, and 6 unassociated sources.
