METHOD FOR PROTECTION FROM PULSE INTERFERENCE AND DEVICE THEREFOR (VERSIONS) Russian patent published in 2015 - IPC G01S7/36 

FIELD: radio engineering, communication.

SUBSTANCE: in the method for protection from pulse interference, which is based on establishing a primary detection threshold and a higher additional threshold, the additional threshold is established in each range interval; features of interference, from which said interference is detected in a radar coverage area, are determined from signals exceeding said threshold. The result according to the first version of the device is achieved due to that a device for protection from pulse interference comprises an antenna, a receiver, a main threshold device, an additional receiving device, an interference selection device, a temporary threshold controller, a synchroniser and an interference recognition device, connected to each other in a certain manner. The result according to the second version of the device is achieved due to that the device for protection from pulse interference comprises an antenna, a receiver, an interference selection device, a second antenna, a second receiver, two main threshold devices with limiters, an additional threshold device with a limiter, two phase detectors, a temporary threshold controller, an interference recognition device and a synchroniser, connected to each other in a certain manner.

EFFECT: generating features of pulse interference and recognition thereof at all range intervals.
