Abstract

In many applications, signals usually consist of multiple linear frequency modulated signal components. To analyze these signals in the joint time-frequency domain, rotational time-frequency transforms are very useful. In this paper, we introduce the basic concept of rotational time-frequency transforms, discuss some properties of the fractional Fourier transform, describe a bilinear generalized-marginal time-frequency transform, and present the Radon transform for line feature detection and estimation. Finally, we apply the rotational time-frequency transform to multiple moving target detection in synthetic aperture radar (SAR) imaging.
