Abstract :
The aim of this work is the performance evaluation for a method used to analyze of a mono-component linear frequency modulation (LFM) signal, based on the quadratic phase function of the signal. A closed form is found for the output signal to noise ratio. The parameter selection problems of the algorithm are also discussed. Thresholds of the input SNR are presented to guarantee a reasonably accurate estimation of the frequency rate at the given signal length. The Monte-Carlo simulations verify the theoretical results.
