An Optimal Shaped Sensor Array Derivation

Micromachines, 2023
In Structural Health Monitoring (SHM) applications, the Direction of Arrival (DoA) estimation of Guided Waves (GW) on sensor arrays is often used as a fundamental means to locate Acoustic Sources (AS) generated by damages growth or undesired impacts in thin-wall structures (e.g., plates or shells).

Optimal node density for two-dimensional sensor arrays [PDF]

2008 5th IEEE Sensor Array and Multichannel Signal Processing Workshop, 2008
The problem of optimal node density for ad hoc sensor networks deployed for making inferences about two dimensional correlated random fields is considered. Using a symmetric first order conditional autoregressive Gauss-Markov random field model, large deviations results are used to characterize the asymptotic per-node information gained from the array.
