英文摘要	In the large high altitude air shower observatory (lhaaso), one square kilometer array (km2a), with 5242 electromagnetic particle detectors (eds) and 1171 muon detectors (mds), is designed to study ultrahigh energy gamma-ray astronomy and cosmic ray physics. the remoteness and numerous detectors extremely demand a robust and automatic calibration procedure. in this paper, a self-calibration method which relies on the measurement of charged particles within the extensive air showers is proposed. the method is fully validated by monte carlo simulation and successfully applied in a km2a prototype array experiment. experimental results show that the self-calibration method can be used to determine the detector time offset constants at the sub-nanosecond level and the number density of particles collected by each ed with an accuracy of a few percents, which are adequate to meet the physical requirements of lhaaso experiment. this software calibration also offers an ideal method to realtime monitor the detector performances for next generation ground-based eas experiments covering an area above square kilometers scale.
