Abstract
Based on the fractional Fourier transform, a time-delay estimator of chirp signals was proposed by Tao in 2009. In this paper, compression performance of the time-delay estimator is discussed in the fractional Fourier domain, referring to linear frequency-modulated pulse compression in the time domain. We find: (a) the pulse-width compression ratio is the product of time duration and band width, denoted as D; (b) the peak amplitude ratio is about D 1/2 when the absolute value of chirp rate is large enough. The conclusions help to the further application of this time-delay estimator based on the FRFT.
