Robustness of oversampled Gabor transient detectors: a comparison of energy and known location detectors

This correspondence provides a “context” for previous studies on the use of linear time-frequency transforms for transient signal detection in the case where signal component locations are assumed to be known. The robustness of a known-location detector (KLD) based on the oversampled Gabor transform is compared with that of the corresponding energy detector in the Gabor domain. As expected, the KLD was sensitive to location mismatch; unexpectedly, it was extremely sensitive to location mismatch
