A direct approach to imaging in a waveguide with perturbed geometry. (arXiv:1810.04705v1 [math.AP])
来源于:arXiv
We introduce a direct, linear sampling approach to imaging in an acoustic
waveguide with sound hard walls. The waveguide terminates at one end and has
unknown geometry due to compactly supported wall deformations. The goal of
imaging is to determine these deformations and to identify localized scatterers
in the waveguide, using a remote array of sensors that emits time harmonic
probing waves and records the echoes. We present a theoretical analysis of the
imaging approach and illustrate its performance with numerical simulations. 查看全文>>
