Spiral-shaped piezoelectric sensors for Lamb waves direction of arrival (DoA) estimation

open access: yes, 2018
A novel strategy to design piezoelectric sensors suited for direction of arrival (DoA) estimation of incoming Lamb waves is presented in this work. The designed sensor is composed by two piezoelectric patches (P1, P2) to be bonded on the structure to be ...

Narrowband and Wideband Direction-of-Arrival Estimation For Uniform And Nonuniform Linear Arrays

open access: yes, 2009
Nonuniform linear arrays (NLAs) have certain advantages and problems for directions of arrival (DOA) estimation. They cover a large array aperture with fewer sensors, and they require fewer matched channels or receivers.
