AIRCRAFT NOSE WITH A DEVICE FOR CALIBRATING AN IR DETECTOR AND CALIBRATION METHOD

摘要

The invention concerns an aircraft nose (100') fitted with an ejectable cap (10) in which the following are located: - a homing head (20) provided with an IR detector (22), a dome (21) and an optical system (24) capable of forming an image of a scene on the IR detector placed in the focal plane (23) of the optical system (24), - a calibration device (25') provided with a temperature reference (251) and an optical system (253) capable of directing the radiation emitted by the temperature reference. The calibration device (25') is placed outside the homing head (20), upstream therefrom such that the calibration optical system (253) is capable of forming an image of the temperature reference (251) on the detector (22) through the dome (21) and the optical system (24) of the homing head, and the calibration device (25') can be ejected with the cap (10).
