		<description><![CDATA[Abstract This paper introduces a novel ESPRIT-based closed form source localization algorithm applicable to arbitrarily spaced three-dimensional arrays of vector hydrophones, whose locations need not be known. Each vector hydrophone consists of two or three identical but orthogonally oriented velocity hydrophones plus one pressure hydrophone, all spatially co-located in a point-like geometry. A velocity hydrophone [...]]]></description>

		<description><![CDATA[Abstract A new type of PVDF hydrophone, the multilayer planar PVDF hydrophone, is described in this paper. The hydrophone disturbs measured acoustic fields very little and has a high sensitivity. The noise equivalent pressure of the hydrophone is 45 dB re 1 μ Pa per Hz  bandwidth.The working freqency range og hyrophon  is 20kHz ~4MHz.In [...]]]></description>

		<description><![CDATA[Abstract The design of a new wideband, quantitative shock wave hydrophone is presented. The sensor not only has a wideband (&#62;SOMHz) and linear (up to 100MPa) response, but it also operates in a measurement environment in which the hydrophone element&#8217;s sensitivity changes as a function of shock wave exposure. Thin films of polyvinylidene difluoride (PVDF) [...]]]></description>
