An Analysis of ISAR Image Distortion Based on the Phase Modulation Effect
EURASIP Journal on Advances in Signal Processing, 2006 Distortion in the ISAR image of a target is a result of nonuniform rotational motion of the target during the imaging period. In many of the measured ISAR images from moving targets, such as those from in-flight aircraft, the distortion can be quite ...

Phase-Distortion-Robust Voice-Source Analysis
, 2012 This work concerns itself with the analysis of voiced speech signals, in particular the analysis of the glottal source signal. Following the source-filter theory of speech, the glottal signal is produced by the vibratory behaviour of the vocal folds and is modulated by the resonances of the vocal tract and radiation characteristic of the lips to form ...

MITIGATION OF HARMONIC DISTORTION USING OPTIMUM PHASE-SHIFT MULTIPLE PARALLEL INVERTERS
Journal of Engineering and Sustainable Development, 2018 It is clear that the harmonics in power systems have many negative impacts and therefore it is inevitable to reduce their amount to the accepted level and one of the interesting approach to reduce the harmonic distortion is to synchronize phase-shifted ...
