METHOD OF PELENGATION OF REPEATER JAMMING AND RADAR INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01S7/38 

FIELD: radio engineering, communication.

SUBSTANCE: in method for determining the direction of the response interference based on the emission of the sounding signal and the survey of the space by the main beam of the phased array antenna, the modulation of the phase or amplitude distribution of the field in the phased array antenna opening is carried out, the direction of the repeater jamming when the relative level of the side lobes of the compressed interference pulse is not above the threshold value. The signals received in zones where reception of the reflected signal from the target is impossible or improbable, and also by the fact that the parameters of the sounding signal are changed by changing the slope of the frequency modulation to the opposite one and the pulses received with the former parameters are considered impulse signals that the threshold is set based on the permissible error in determining the bearing. The device for carrying out the method includes a phased array antenna, a drive, a receiver, a pulse compression device that is optimally matched to a pulse having a positive slope of the frequency modulation "+", a threshold device, a bearing formator, a second pulse compression device, a second pulse compression device, optimally matched to a pulse having a negative slope of the change in the frequency modulation "-", a frequency modulation switch, switch synchronous control device, the input of which is the input of an external signal "Enabling the modification of the signal parameters", three-delayed delay line, pulse ratio device, modulation frequency generator, field distribution modulation device of phased array antenna, connected in a certain way.

EFFECT: increase the accuracy of determining the direction of the producer of the response interference, including in the case of instability of its level.
