Target detection for depth imaging using sparse single-photon data


This paper presents a new Bayesian model and associated algorithm
for depth and intensity profiling using full waveforms from timecorrelated
single-photon counting (TCSPC) measurements when the
photon count in very low. The model represents each Lidar waveform
as an unknown constant background level, which is combined
in the presence of a target, to a known impulse response weighted
by the target intensity and finally corrupted by Poisson noise. The
joint target detection and depth imaging problem is expressed as a

Time Delay Estimation: Applications and Algorithms


Time delay estimation refers to finding the time-differences-of-arrival between signals received at an array of sensors. In this presentation, representative applications of time delay estimation are first described. Algorithms for accurately estimating the time difference between two sensor outputs using random and deterministic signals are then presented and analyzed.
