Semi-coherent time of arrival estimation using regression

The Journal of the Acoustical Society of America, 2012
Time of arrival (ToA) estimation is essential for many types of remote sensing applications including radar, sonar, and underground exploration. The standard method for ToA estimation employs a matched filter for computing the maximum likelihood estimator (MLE) for ToA.

Indoor distance estimation by using time of arrival

2018 26th Signal Processing and Communications Applications Conference (SIU), 2018
Nowadays, researches about indoor positioning is very popular. Estimating location of a communication node can be used in navigation in a shopping mall or tracking in a work place, etc. In applications without a reference point, relative location of the nodes is preferred.

Interference Mitigation for Time of Arrival Estimation

2010 IEEE Wireless Communication and Networking Conference, 2010
In indoor environments, geolocation using Time of Arrival (TOA) estimation must use a wide bandwidth to overcome the effects of multipath propagation. Narrowband interference from other applications is a significant problem. In this paper we investigate a number of signal processing schemes to detect and overcome one or more relatively narrowband ...

Time-of-arrival estimation in path attenuation

2009 IEEE 10th Workshop on Signal Processing Advances in Wireless Communications, 2009
We consider a time-of-arrival (ToA) estimation in the presence of path attenuation. Maximum correlation (MC) is revisited and maximum likelihood (ML) is newly derived to estimate the ToA. It reveals that for low effective bandwidth, short distance and large path loss exponent, the ML has a smaller error variance than the MC.

Space-time localization using times of arrival

2011 49th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2011
We provide a computationally efficient framework for utilizing Time of Arrival (ToA) sensors to localize multiple events in close proximity in space and time. Conventional ToA-based localization algorithms are typically designed for single events. Na¨ive approaches for associating ToAs with events and then applying a conventional localization algorithm

Time-of-arrival measurement for transionospheric EMP

MILCOM 92 Conference Record, 2003
An ionospheric-delay correction model that measures the time of arrival (TOA) of a transionospheric electromagnetic pulse (EMP) is presented. The pulse-broadening effect due to the dispersive ionosphere is incorporated into the ionospheric group-delay model to provide an improved delay correction in measurements of EMP time of arrival.

THEORY OF QUANTUM FIRST TIME OF ARRIVAL VIA SPATIAL CONFINEMENT I: CONFINED TIME OF ARRIVAL OPERATORS FOR CONTINUOUS POTENTIALS

International Journal of Modern Physics A, 2006
The constructions of two classes of self-adjoint and compact first time of arrival operators for confined systems under arbitrary, everywhere continuous potential are detailed, extending in the interacting case the concept of confined quantum time of arrival operators first developed for the free particle.

POSITION FIXING BY TIME OF ARRIVAL

1966
Abstract : An engineering model is developed of the error contours encountered in position fixing using synchronous time of arrival data. Normal distribution is emphasized. Probabilities of fixes occurring within circles and ellipses are determined using the natural oblique coordinates associated with the measuring system. Comparisons are made of three-
