On the Fractional Wideband and Narrowband Ambiguity Function in Radar and Sonar
Get PDFThe article of record as published may be found at http://dx.doi.org/10.1109/LSP.2006.874436We 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.This work was sponsored by the Office of Naval Research
