Comparison of the operation of an acousto-optic spectrum analyzer and an acousto-optic pseudo-Wigner processor by analyzing the time-frequency distributions of frequency-modulated signals
This paper compares the accuracy of the time-frequency distributions and their resolving power in the frequency-time plane of frequency-modulated radio signals when they are obtained by means of an acousto-optic spectrum analyzer and a pseudo-Wigner processor. Signals with linear frequency modulation and signals in which the frequency depends on time to a power greater than the first are considered. The results of numerical modeling are presented.
