DEVICE FOR DIRECTION LOCALISATION ON SOURCE OF ELECTROMAGNETIC RADIATION Russian patent published in 2009 - IPC G01S3/02 

FIELD: physics, measuring.

SUBSTANCE: invention concerns field of devices for direction definition on a radiation source, in particular to devices for direction definition on a radiant of electromagnetic radiation. The device for direction localisation on the source of electromagnetic radiation, contains the truncated parabolic mirror, system of three round diaphragms, coaxial with the parabolic mirror, one of which, with small round paraxial hole, settles down in a plane of truncation of a parabolic mirror, second, continuous, on some distance from the first with possibility of travel along an axis of a parabolic mirror, the third, continuous diaphragm of variable radius, on some distance from the second diaphragm. The data units fixing presence of radiation in the given solid angle of space are located on the device output.

EFFECT: decrease in probability of detection of the device by resorts of a detection and ranging and simplification of adjustment of the device.
