The searching completion of Near-Earth Asteroids (NEAs) is the premise of planetary defense.%In order to evaluation the observation efficiency of Near-Earth Asteroids, an observation efficiency evaluate method is proposed, which includes telescope parameters and station conditions.In order to quantify the observation efficiency of NEAs, a method for evaluating the observation efficiency is proposed, which includes telescope parameters and station conditions.Considering the signal-to-noise ratio of target and the NEAs visibility model, detect condition and evaluation index are defined to evaluate the observation efficiency. Then, based on the NEAs orbit data and the size distribution model, the simulated NEAs orbit database is established. Finally, two observation stations, Xuyi and Lenghu, are chosen for simulation analysis. The results show that without considering the effective observation time, the observation efficiency of CNEOST (China Near-Earth Object Survey Telescope) in Lenghu increased by 5.21 times than in Xuyi within one month. Compared to Xuyi station, Lenghu station has more advantages in observing smaller NEAs. It could also provide better observation efficiency for targets not found.
