Time-Delay Estimation From Low-Rate Samples: A Union of Subspaces Approach
Kfir Gedalyahu,Yonina C. Eldar +1 more
TL;DR: A unified approach to time delay estimation from low-rate samples, combining results from sampling theory with those obtained in the context of direction of arrival estimation, to ensure perfect recovery of the channel parameters at the minimal possible rate.
Journal ArticleDOI
Cramer-Rao bounds for estimating range, velocity, and direction with an active array
TL;DR: The volume of the confidence region for the target's location is proposed as a measure of accuracy and it is shown that the highest (and lowest) target location accuracy is achieved if the target lies along one of the principal axes of inertia of the array.

Three-Dimensional Wideband Beamforming for Imaging Through a Single Wall
TL;DR: This letter extends the analysis to 3D imaging via delay-and-sum beamforming in the presence of a single uniform wall to provide valuable information on target heights that can be used for enhancing target discrimination/identification.

Optimum beam steering of linear phased arrays
Shi-Chang Wooh,Yijun Shi +1 more
TL;DR: In this article, a model was developed to compute acoustic pressure distribution of the waves radiated from an ultrasonic linear phased array, and beam directivity and steerability were studied for various transducer parameters such as number of elements, inter-element spacing, element width, and transducers frequency.
