This paper presents a tutorial review of work in coherence and time delay estimation. A
review of coherence research and development is presented. A derivation of the ML …

This paper introduces a new velocity estimator, referred to as the 2D autocorrelator, which
differs from conventional Doppler techniques in two respects: the derivation of axial velocity …

An overview of applied research in passive sonar signal processing estimation techniques
for naval systems is presented. The naval problem that motivates time delay estimation is the …

The estimate of the difference in time of arrival of a common random signal received at two
sensors, each of which also receives uncorrelated noise, is examined for both small and …

Leakage detection based on acoustic leak noise correlation in particular, has drawn the
attention of the research community in recent years, as it is a conceptually simple, non …

The application of dyadic wavelet decomposition in the context of time delay estimation is
investigated. We consider a model in which the source signal is deterministic and the …

The problem of estimating the difference in arrival times of a non-Gaussian signal at two
spatially separated sensors is considered. The signal is assumed to be corrupted by …

The last fifteen years have witnessed a tremendous resurgence in research and applications
in the area of higher-order statistics (HOS), a broad term encompassing statistical …

Tissue motion and elasticity imaging techniques commonly use time delay estimation (TDE)
for the assessment of tissue displacement. The performance of these techniques is limited …

A computationally efficient method for phase aberration correction in ultrasound imaging is
presented. The method is based on time delay estimation via minimization of the sum of …
