Optimal design of linear array of sensors
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991The authors address the issue of design of linear arrays of sensors with application to high-resolution direction-of-arrival (DOA) algorithms, and present the D-optimality based design criterion (DOBC). The design technique employs certain prior information in the cases of low-angle tracking and where targets are close to each other, and provides an ...

Optimization of monolithic charged-particle sensor arrays
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007Abstract Direct-detection CMOS image sensors optimized for charged-particle imaging applications, such as electron microscopy and particle physics, have been designed, fabricated and characterized. These devices directly image charged particles without reliance on image-degrading hybrid technologies such as the use of scintillating materials.

Optimizing an array of sensors for magnetoencephalography
Proceedings of 17th International Conference of the Engineering in Medicine and Biology Society, 2002Modern magnetoencephalographic (MEG) instruments estimate the location of endocranial current sources with an array of magnetometers. The authors provide a technique for computing the magnetometer orientations that achieve minimum mean-square localization error.

Vector sensors and vector sensor line arrays: Comments on optimal array gain and detection
The Journal of the Acoustical Society of America, 2006This paper examines array gain and detection performance of single vector sensors and vector sensor line arrays, with focus on the impact of nonacoustic self noise and finite spatial coherence of the noise between the vector sensor components. Analytical results based on maximizing the directivity index show that the particle motion channels should ...

Optimal detection with vector sensors and vector sensor line arrays
The Journal of the Acoustical Society of America, 2006The detection performance of single vector sensors and vector sensor line arrays is degraded by nonacoustic self-noise and spatial coherence of the noise between vector sensor components. Results based on optimizing the directivity index for a single vector sensor show that the particle motion channels should always be included in the processing for ...

Optimal dimension reduction for sensor array signal processing
[1991] Conference Record of the Twenty-Fifth Asilomar Conference on Signals, Systems & Computers, 1993The computational complexity for direction-of-arrival estimation using sensor arrays increases very rapidly with the number of sensors in the array. One way to lower the amount of computations is to employ some kind of reduction of the data dimension. This is usually accomplished by employing linear transformations for mapping full dimension data into ...

Optimal positioning of sensors for a microphone array
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002Sensor positioning has an important influence on the performance of array processing. The main contributions of the paper are the proposal of criteria to evaluate and to optimize the performance of an array of sensors through its geometric configuration, the number and the positions of the sensors.

TDOA sensor array optimization using Digital Elevation Model
2017 Iranian Conference on Electrical Engineering (ICEE), 2017This paper addresses the problem of optimizing TDOA sensor locations using Digital Elevation Model (DEM). The aim of this work is to obtain an effective procedure to emplace TDOA sensors in a large geographical scale taking the number of sensors, the accuracy of position estimation and the coverage into account.

Optimization of sensor arrays for beam position estimation
Sensors and Actuators A: Physical, 2000A design procedure is presented to optimize linear arrays of sensors for the estimation of the position of an incident beam. The procedure is based on the adjustment of the position and gain of the elements of the array in order to approximate the desired response (in the least squares sense).
