A Comparison of the Newly Proposed Gabor Order Tracking Technique vs. Other Order Tracking Methods

A new method for extracting order related signal components from rotating machinery data is proposed. The notion of the Gabor expansion and the Gabor transform for time/frequency analysis are introduced and the relationship between them is described. Gabor Order Tracking (GOT) is offered as one possible masking strategy for extracting desired signal components from the time/frequency domain for reconstruction in the time domain. Practical examples are utilized to illustrate the proposed method in comparison to established techniques.
