METHOD FOR PHYSICAL MODELLING OF THE BACKGROUND-TARGET ENVIRONMENT FOR TESTING ON-BOARD OPTOELECTRONIC SEEKERS Russian patent published in 2023 - IPC G01M11/02 F41G3/32 G02B27/30 

FIELD: test equipment; on-board optoelectronic seekers.

SUBSTANCE: invention is intended for testing on-board optoelectronic seekers. The method of physical modelling of the phono-target environment for testing on-board optoelectronic seekers is characterized by the fact that a flat mirror with holes is used as the test object channel, behind which is a black body model, and a collimator mirror that transmits images of holes from temperature of the blackbody model to the entrance pupil of the on-board optoelectronic seekers, and as the background emitter channel, a low-temperature blackbody model and a projection lens are used, consisting of two spherical mirrors and forming an image of the low-temperature blackbody model on a flat mirror with holes in the test object channel, which is then transmitted to the entrance pupil of the on-board optoelectronic seekers through the collimator mirror of the test object channel.

EFFECT: expansion of functionality for testing on-board optoelectronic seekers and the reproduction of the temperature contrast between the test object and the background in a wide temperature range - from 0.5 to 100 K.
