Engineering Physics Annotation << Back GLOBAL SEISMIC ANTENNA AS GRAVITATIONAL TELESCOPE A.V. LUKANENKOV Global seismic antenna (GSA) allows detecting deformations of the Earth of a special type, characteristic of gravitational waves. GSA elements - the arbitrary «quiet» seismic stations, aperture of GSA must be of the order 10.000 km. Pulsars are a natural source of periodic gravitational waves (GW-waves). The deformations of the Earth were detected by GSA, their amplitude ≈2.5·10-15 m. It was found that these deformation (strain) of the order h≈10-21. The false alarm of detecting is almost zero, equivalent to a signifi cance of 12.8 sigma. Pulsar J0945-4833 is the most suitable source of detected deformations of the Earth. Key words: gravitational waves, gravitational signal, gravitational telescope, seismic antenna, deformation, optimal signal processing. Contacts: E-mail: a_v_luk@mail.ru Pp. 48-59.
