Confined Quantum Time of Arrivals [PDF]
Physical Review Letters, 2004 We show that formulating the quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding states that evolve to unitarily collapse at a given point at a definite time. For the spatially confined particle, we show that the problem admits a solution in the form of an eigenvalue problem ...

Measurement of time of arrival in quantum mechanics [PDF]
Physical Review A, 1998 It is argued that the time-of-arrival cannot be precisely defined and measured in quantum mechanics. By constructing explicit toy models of a measurement, we show that for a free particle it cannot be measured more accurately then $Δt_A \sim 1/E_k$, where $E_k$ is the initial kinetic energy of the particle. With a better accuracy, particles reflect off

Time-of-arrival formalism for the relativistic particle [PDF]
Journal of Physics A: Mathematical and General, 1997 A suitable operator for the time-of-arrival at a detector is defined for the free relativistic particle in 3+1 dimensions. For each detector position, there exists a subspace of detected states in the Hilbert space of solutions to the Klein Gordon equation.

Confined quantum time of arrival for the vanishing potential [PDF]
Physical Review A, 2005 We give full account of our recent report in [E.A. Galapon, R. Caballar, R. Bahague {\it Phys. Rev. Let.} {\bf 93} 180406 (2004)] where it is shown that formulating the free quantum time of arrival problem in a segment of the real line suggests rephrasing the quantum time of arrival problem to finding a complete set of states that evolve to unitarily ...

Super-Resolution Time of Arrival Estimation Using Random Resampling in Compressed Sensing [PDF]
, 2018 There is a strong demand for super-resolution time of arrival (TOA) estimation techniques for radar applications that can that can exceed the theoretical limits on range resolution set by frequency bandwidth.

Low-Complexity Wideband Interference Mitigation for UWB ToA Estimation
Sensors, 2023 Reliable time of arrival (ToA) estimation in dense multipath (DM) environments is a difficult task, especially when strong interference is present. The increasing number of multiple services in a shared spectrum comes with the demand for interference ...

Probabilistic Time of Arrival Localization [PDF]
IEEE Signal Processing Letters, 2019 In this paper, we take a new approach for time of arrival geo-localization. We show that the main sources of error in metropolitan areas are due to environmental imperfections that bias our solutions, and that we can rely on a probabilistic model to learn and compensate for them.

Optimal Passive Source Localization for Acoustic Emissions
Entropy, 2021 Acoustic emission is a non-destructive testing method where sensors monitor an area of a structure to detect and localize passive sources of elastic waves such as expanding cracks.
