METHOD OF JAMMING OPTOELECTRONIC COORDINATOR OF HOMING ELEMENT FROM LASER RADIATION Russian patent published in 2025 - IPC F42B15/01 

FIELD: communication technique.

SUBSTANCE: invention relates to the field of homing systems noise immunity. Method of noise protection of an optoelectronic coordinator (OEC) of a homing element (HE) from laser radiation is based on reception of optical radiation of an OEC object, includes the main and additional photodetectors (PD). Additional photodetector (APD) is of a ring type with its ring centre located on the optical axis and as close as possible to the focal plane of the OEC and with the orientation of the field of view of each of its photosensitive elements to the centre of the APD. When optical radiation of the object is detected by the main photodetector, parameters of its output signals are measured and angular parameters of the object location are determined from their values. Operability of the main PD is monitored. After establishing the fact of inoperability of the main photodetector, the inner space of the OEC is additionally filled with a gaseous substance with a given scattering index of laser radiation, which provides the required detecting ability of the APD. When detecting an APD scattered sideways by a gaseous medium, the coordinates of the location of its PSE are determined, the signals at the output of which have exceeded the threshold value, and values of the output signals of its PSE are measured. Further, using the values of the output signals of the APD PSE and values of their coordinates, the values of the given radius of the circle formed by the ADP PSE and spatial parameters of the setup of the APD in the OEC, and the angular parameters of the location of the laser radiation are determined.

EFFECT: high detecting ability of the OEC on an additional receiving channel.
