CRB-optimal sensor placement for multiple passive acoustic arrays
2013 IEEE Global Conference on Signal and Information Processing, 2013This paper describes a method for selecting the location of multiple passive acoustic arrays to optimize information collection. The passive acoustic arrays are used to localize a contact, and our goal is to choose how to situate and orient the arrays to optimize this localization estimate. To this end, we derive the Cramer-Rao bound on the variance of

Large-Scale Optimal Sensor Array Management for Multitarget Tracking
IEEE Transactions on Systems, Man and Cybernetics, Part C (Applications and Reviews), 2007In this paper, we are concerned with the problem of utilizing a large network of sensors in order to track multiple targets. Large-scale sensor array management has applications in a number of target tracking domains. For example, in ground target tracking, hundreds or even thousands of unattended ground sensors may be dropped over a large surveillance

Optimal sensor placement in range based localization for linear arrays
2012 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2012This paper investigates the linear separation requirements for range sensors in order to achieve the optimal performance in estimating the position of a target from multiple and typically noisy sensor measurements. We analyze the sensortarget geometry in terms of the Cramer-Rao inequality and the corresponding Fisher information matrix, in order to ...

Asymptotic performance of optimal gain-and-phase estimators of sensor arrays
IEEE Transactions on Signal Processing, 2000This paper deals with the asymptotic behavior of optimal gain-and-phase estimators of sensor arrays. Three well-known algorithms for estimating angles of arrival are the following: (i) weighted noise subspace fitting (WNSF), (ii) unconditional maximum likelihood (UML), (iii) conditional maximum likelihood (CML).

Optimization of beam patterns for acoustic array sensors
Sensors and Actuators A: Physical, 1994Abstract Acoustic sensors comprising beam-forming and electronic scanning equipment typically use a cylindrical multi-element transducer. When received signals are added without any delays, a wide-beam sensor is obtained. Unfortunately, the shape of the beam and the level of the side lobes is often far from satisfactory.

About estimation of optimal number of sensors in sensor array system based on PARAFAC decomposition
2012 8th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2012Identification of multiple sources in sensor array system can be accomplished by a powerful multilinear algebra model, PARAFAC (parallel factor) decomposition. To guarantee the accuracy of the identification of close sources (the smallest angle difference is 1°) by PARAFAC algorithm, increasing the number of sensors is a solution.

Design and optimization of nanogap array sensors
2008We present a percolation based model which is suitable for the design of sensors based on highly ordered nanogap arrays. Monte-Carlo simulations and analytical expressions are used to calculate the sensitivity and dynamic range as a function of the topology and geometry of the arrays, as well as the statistical distribution of the thresholds for ...
