DEVICE FOR DISTINGUISHING CHIRP SIGNALS Russian patent published in 2015 - IPC H04B1/10 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to pulsed information receivers and can be used in electronic surveillance and target designation stations. The result is achieved due to that the device includes an autocorrelator, two threshold elements, a switch, an interval-to-code converter, three registers, two dividers, three coincidence units, an envelope detector, a comparator, a univibrator, a clock generator, two delay lines, a bidirectional counter, an RS flip-flop, an AND element and an adder. The listed devices are connected to each other in a certain manner.

EFFECT: higher sensitivity of the device while providing high reliability of distinguishing signals.
