METHOD OF DETERMINING PARAMETERS OF CHIRP SIGNALS Russian patent published in 2016 - IPC G01S13/00 

FIELD: radio engineering, communication.

SUBSTANCE: method is carried out by determining radial velocities of radio-frequency source and receiver carriers, the average wavelength of chirp signals, measuring the period of chirp signals and determining the spectral width of chirp signals using the formula: where f_d(n) is the difference frequency of the signal at the output of the autocorrelation receiver, τ_d is the delay time of the received chirp signal, τ_u is the duration of the chirp signal, V_rS(nT_u) is the radial velocity of the radio-frequency source carrier, V_rR(nT_u) is the radial velocity of the receiver carrier, T_u is the period of chirp signals, λ is the average wavelength of chirp signals, $$n=\overline{1\dots N},$$ N is the number of chirp signals.

EFFECT: improving the accuracy of determining the spectral width of a chirp signal by taking into account the relative motion of the radio-frequency source carrier and the autocorrelation receiver carrier.
