METHOD FOR ENSURING ELECTROMAGNETIC COMPATIBILITY OF PULSE-DOPPLER ONBOARD RADAR STATIONS OF A GROUP OF FIGHTERS Russian patent published in 2021 - IPC G01S13/52 G01S13/87 

FIELD: radars.

SUBSTANCE: invention relates to the field of radar and can be used to ensure electromagnetic compatibility (EMC) of pulse-Doppler airborne radar stations (ABRS) of a group of fighters when they work together for radiation. The claimed method consists in the fact that all the pulse-Doppler onboard radars of the fighters of the group are combined into a single radar system with channels for mutual exchange of information; one fighter-leader with its onboard radar station is assigned to the group. When all the radar stations operate on radiation on the leader fighter, taking into account the transmitted information about the direction of flight of each fighter, its spatial position and the field of view by the main lobe of the antenna directional diagram, data is generated on the location of each i-th receiver of the on-board radar of fighters of the group in the field of view by the main the lobe of the antenna pattern of a pulse-Doppler radar station equipped with the j-th transmitter. When the i-th on-board radar receiver is in the survey sector with the main lobe of the antenna pattern of a pulse-Doppler radar station equipped with the j-th transmitter, an analysis of the frequency compatibility of the on-board radar data is carried out. In case of incompatibility of the operating frequencies of the data of the on-board radar on the on-board radar equipped with the j-th transmitter, a ban on radiation in the direction of the on-board radar equipped with the i-th receiver is carried out. Further, the radar station of each fighter of the group carries out a survey of the space, taking into account the prohibitions on radiation in the direction of the corresponding fighters of the group.

EFFECT: EMC support of the pulsed-Doppler radar system of a group of fighters when they work together for radiation without changing the relative position of fighters in the group.
