METHOD FOR RECEIVING AND PROCESSING SIGNALS OF THE AIR TRAFFIC CONTROL SYSTEM UNDER THE INFLUENCE OF NOISE AND PULSE INTERFERENCE Russian patent published in 2022 - IPC H04B1/10 

FIELD: radar technology.

SUBSTANCE: invention relates to radar technology and can be used for receiving and processing signals of systems based on the principles of active radar. In the method for receiving and processing signals of the air traffic control system under the influence of noise and pulse interference, counting the number of pulses of the received signal from the output of the receiving device that exceeded a certain threshold during one cycle of operation is used, and based on this, a decision is made on the presence of interference requiring compensation. The method uses lower and upper detection thresholds, the response levels of which differ by a constant fixed amount sufficient to exclude the possibility of exceeding the upper threshold by individual noise emissions. The calculation of the number of noise emissions that have exceeded the threshold, and the decision on the basis of this decision to simultaneously decrease or increase both detection thresholds is made using the lower threshold, and the detection of useful signal pulses is carried out by exceeding the upper threshold.

EFFECT: improving the quality of reception and subsequent processing of a useful signal under the influence of noise and pulse interference.
