Abstract :
A solution to the problem of undesired cross-terms in the Wigner distribution (WD) of two-dimensional real signals is presented. The solution is to introduce the notion of two-dimensional analytic signal in the WD. The relation between WDs of the two-dimensional real signal and those of its associated two-dimensional analytical signal is discussed and illustrated by an example
