  The High Altitude Detection of Astronomical Radiation (HADAR) experiment is a
refracting terrestrial telescope array based on the atmospheric Cherenkov
imaging technique. It focuses the Cherenkov light emitted by extensive air
showers through a large aperture water-lens system for observing
very-high-energy-rays and cosmic rays. With the advantages of a large
field-of-view (FOV) and low energy threshold, the HADAR experiment operates in
a large-scale sky scanning mode to observe galactic sources. This study
presents the prospects of using the HADAR experiment for the sky survey of TeV
{\gamma}-ray sources from TeVCat and provids a one-year survey of statistical
significance. Results from the simulation show that a total of 23 galactic
point sources, including five supernova remnant sources and superbubbles, four
pulsar wind nebula sources, and 14 unidentified sources, were detected in the
HADAR FOV with a significance greater than 5 standard deviations ({\sigma}).
The statistical significance for the Crab Nebula during one year of operation
reached 346.0 {\sigma} and the one-year integral sensitivity of HADAR above
1TeV was ~1.3%-2.4% of the flux from the Crab Nebula.
