The maximum value of the normalized ambiguity function is one. 4.0 AMBIGUITY FUNCTION 4.1 INTRODUCTION We now turn our attention to the ambiguity function. The ambiguity function, which is denoted as FW f,, is primarily used to gain an understanding of how a signal processor responds, or reacts, to a given returned signal. As The zero Doppler cut of the ambiguity function depicts the matched filter response of a target when the target is stationary. From the plot, one can see that the first null response appears at 10 microseconds, which means that this waveform could resolve two targets that are … ambiguity function is established in this correspondence after deﬁning the Teager operator over complex-valued signals. This relation allows the use of the Teager energy in estimating the second moment angular bandwidth and the moments of a signal duration (spread) and that of its spectrum.

and large error properties. The ambiguity function establishes global conditions under which the local bounds are accurate predictions of the expected error performance and identiﬁes the regions of the parameter space where large errors may occur.

INTRODUCTION WebHome < ARL < TWiki biguity function is an effective analytical tool, but it is not sufficiently well understood to serve as effectively as a synthesis tool. Gradually this difficulty is being overcome as the list of properties and theorems on ambiguity functions appearing in the literature increases [l]-[la]. PDF | Like the Wigner function, the Ambiguity function provides an elegant way to describe the propagation of a partially coherent beam in free space or | Find, read and cite all the research Wasow et al. (2005) also suggest ambiguity might be use-ful in language contact situations, where speakers of both languages should ideally be able to handle words meaning two different things in two different situations.

1.1. Pragmatic ambiguity of deontic sentences The pragmatic ambiguity of deontic sentences is a very well known phenomenon in speech acts theory.1 This phenomenon has been isolated by the German logician Christoph Sigwart [1830-1904].
