摘要：
Gabor Wigner transform (GWT) avoids the cross terms and gives high clarity in time frequency (t-f) domain. The transform is however unable to provide a clear picture in situations when auto and cross components of Wigner transform of the multi component signal overlap. This paper presents a new simple hybrid approach that overcomes the limitations of GWT in an efficient manner by making use of fractional Fourier transform and image processing technique. Experimental results demonstrate superiority of proposed scheme.
