DELAY-DOPPLER AMBIGUITY FUNCTION FOR WIDE-BAND SIGNALS.
Abstract
The conventional ambiguity function is extended to include the Doppler distortions of the modulation function. The distinctive features of the extension are the use of the complex notation for wide-band signals, and inclusion of the Doppler effect on the signal amplitude. The result is an ambiguity function from which Woodward's form can be found by inspection. It is shown that the well-known volume constraint also applies, in unchanged form, to the generalized ambiguity function. For the volume to be constant, it is not required that the distortions of the modulation function be neglected. Rather, the volume constancy is related to the sinusoidal fluctuations of a modulated-carrier type signal and thus is strictly a matter of the percentage bandwidth of the signal. (Author)
