Abstract
We construct the wideband ambiguity function
for signals represented by their fractional Fourier transforms.
Because the reflected signal must be represented as a Doppler
scaled version of the transmitted signal, this wideband form of
ambiguity does not enjoy many of the same properties as the
narrowband form (which is formed from a Doppler shifted version
of the signal). We present the general result and also examine an
approximation appropriate to wideband signals reflected from
slowly moving targets.
