Localization of Radiating Sources by an Acoustical Array
Arrays of sensors are used in many fields to detect signals, to resolve closely spaced targets, to estimate the bearing, the position, the strength and other properties of radiating sources whose signals arrive from different positions. The purpose of the work is described in the paper is to provide estimators which are used to localize acoustical sources by an acoustical array of sensors. Thes...
متن کاملA refined wideband acoustical holography based on equivalent source method
This paper is concerned with acoustical engineering and mathematical physics problem for the near-field acoustical holography based on equivalent source method (ESM-based NAH). An important mathematical physics problem in ESM-based NAH is to solve the equivalent source strength, which has multiple solving algorithms, such as Tikhonov regularization ESM (TRESM), iterative weighted ESM (IWESM) an...
متن کاملAn application of holographic interferometry to acoustical holography
Holographic interferometry with a phase-modulated reference beam is applied to an acoustic holography. A very thin, flexible, optically reflective membrane, called a pellicle, is used in the liquid as an acousto-optic interface. The method involves three processes: the motion of a pellicle caused by an ultrasonic wave is recorded as an optical hologram using holographic interferometry; the opti...
متن کاملFast wideband acoustical holography.
Patch near-field acoustical holography methods like statistically optimized near-field acoustical holography and equivalent source method are limited to relatively low frequencies, where the average array-element spacing is less than half of the acoustic wavelength, while beamforming provides useful resolution only at medium-to-high frequencies. With adequate array design, both methods can be u...
متن کاملWideband acoustical holography
Patch Near-field Acoustical Holography (NAH) methods like SONAH and ESM are limited to relatively low frequencies where the average array inter-element spacing is less than half a wavelength, while beamforming provides useful resolution only at medium-to-high frequencies. With adequate array design, both methods can be used with the same array. But for holography to provide good low-frequency r...
