Engineering Physics Annotation << Back Gravitational signal detector Lukanenkov A.V. As a detector of gravitational signal is proposed to use a global seismic antenna (GSA), and its elements – arbitrary «quiet» seismic station antenna aperture to be about 10 000 km. In this paper we consider the variant of GSA based on the 19 seismic stations of the International Monitoring System (IMS) of the Comprehensive Nuclear Test Ban Treaty (CTBT) on different continents of the Earth. Seven signals detected using optimal processing of seismic data of the global seismic antenna with a confidence probability Pconf  > 0,97. These signals lie in planes perpendicular to the direction on specific points of the celestial sphere, have elliptical polarization close to 90 %. Verified that they cause deformation (curvature) of space of the order of 10–21. The speed of the detected signals VS > 1,793·108 m/s. Frequency of detected signals are close to the frequencies of known pulsars (±0,05 Hz) and the coordinates of these pulsars lie near the region of maximum values of the energy of the detected signals. Key words: gravitational waves, gravitational signal, gravitational detector, experiment, seismic antenna, seismic station, deformation, elliptical polarization, radiation pattern, optimal signal processing.
