Detection of time of arrival of ultrasonic pulses
Journal of Physics: Conference Series, 2006 Applications exist that employ transit-time measurements to determine distances to scattering objects. These include blood-flow measurements, fluid-level detection, nondestructive testing of materials, image processing of geometrical bodies etc. Many of these require extreme accuracy in measuring transit time through a medium.

High resolution time of arrival estimation for a cooperative sensor system [PDF]
Advances in Radio Science, 2010 Distance resolution of cooperative sensors is limited by the signal bandwidth. For the transmission mainly lower frequency bands are used which are more narrowband than classical radar frequencies. To compensate this resolution problem the combination of

Measuring pulse times of arrival from broad-band pulsar observations [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 In recent years, instrumentation enabling pulsar observations with unprecedentedly high fractional bandwidth has been under development which can be used to substantially improve the precision of pulsar timing experiments. The traditional template-matching method used to calculate pulse times-of-arrival (ToAs), may not function effectively on these ...

Two-Step Time of Arrival Estimation for Pulse-Based Ultra-Wideband Systems
EURASIP Journal on Advances in Signal Processing, 2008 In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information.
