In radar communication, the ambiguity function plays an important role in estimating the delay and Doppler shift introduced in received signal. With the limitation of ambiguity function based on Fourier transform, the FRFT based ambiguity function has been introduced. But it imposes a large computational complexity in the problems where only delay and Doppler shift is needed to estimate. In this article, a new method is introduced to estimate delay and Doppler shift based on the FRFT of received echo signal.
