Abstract
The time delay estimation for linear frequency-modulated (LFM) pulse based on the fractional Fourier transform was analyzed in the fractional Fourier domain, taken the time domain performance of linear frequency-modulated pulse compression as reference. Also, the difference between these two methods was discussed in digital signal processing. It is found that they have almost the same output signal to noise ratio, pulse-width compression ratio and peak amplitude ratio. Furthermore, the latter has higher precision in the time delay estimation in digital implementation, needs less data rate, and has more potential.
