The receiving array in passive systems such as towed arrays or wide aperture ranging arrays must be able to detect signals with unknown frequency content, and therefore must operate over a frequency ...

Hydrophones are underwater acoustic sensors, which most commonly use piezoelectric technology. They can be used singly or in arrays that can contain dozens or hundreds of individual units. They are ...

The Allen Telescope Array (ATA) is the first radio telescope to be designed from the ground up to be used for SETI searches.Until its construction, all radio SETI efforts were dependent on the ...

Figure 2: Seismic data from the hydrophone at 2100 m from the airgun source array, which was fired every 20 seconds. Gaps, for example between SP 700 and 750, occur where firing of the source array ...

Project CETI (Cetacean Translation Initiative) aims to collect millions to billions of high-quality, highly contextualized ...

Cutting edge geophysical imaging tools are available within the Department of Geology and Geophysics. The UW Near Surface Geophysics Instrumentation Center (UWNSG), housed in the Bill Nye Warehouse, ...

There have been an array of theories since the jet disappeared ... The doctor and his team analysed hundreds of hours' worth of hydrophone data from hydroacoustic stations to try and find ...
