DEVICE FOR ANALYSING MODULATION PARAMETERS OF COMPOSITE RADAR SIGNALS Russian patent published in 2014 - IPC H04B1/10 

FIELD: radio engineering, communication.

SUBSTANCE: device has a phase-shift keyed (PSK) signal processing channel, series-connected autocorrelator, frequency deviation metre, a switching unit and series-connected control pulse former and chirp signal characteristic generating unit, wherein the first input of the PSK signal processing channel is connected to inputs of the autocorrelator and the control pulse former, and the second and third inputs are connected to the first and second outputs of the control pulse former and the second and third inputs of the frequency deviation metre, and two outputs are connected to second and third inputs of the switching unit, respectively, the fourth input of which is connected to the output of the chirp signal characteristic generating unit. The device also includes, between the second output of the control pulse former and the second input of the chirp signal characteristic generating unit, series-connected first delay line and switch and second delay line and switch, wherein the second input of the first switch is connected to the output of the autocorrelator and the second input of the second switch is connected to the input of the first delay line.

EFFECT: high reliability of determining the type of modulation of radar signals.
