Abstract: Referring to HB 6750-93 General Requirements for Calibration and Calibration of Airborne Weapon Fire Control Systems,aiming at the existing issues of calibration process models,such as low applicability,large area occupation,heavy equipment,low efficiency,complex operation and low accuracy,an intelligent on-site calibration system is constructed based on ABE system and intelligent theory,and research on key technologies which including benchmark axis measurement,target screen simulation and weapon axis pointing guidance is carried out,and an intelligent target calibration device for armed helicopters is developed，which can realize lightweight,intelligent,and precise targeting in free scene.

Key words: ABE, Armed helicopter, Intelligent target calibration
