Abstract :
In this work observations are discussed in the response of the gravitation signal of the sounding inclined Doppler of the low acoustic (LFA) and internal gravitation (IGW) of waves in upper atmosphere, formed from pulsed sources: the process of earthquake preparing; the start of the rocket. In both events sources have broadband (/spl delta/-figurative) spectrum. The difference is concluded that in the process of preparing the earthquake source is found on land surfaces, and at the stairwell of a rocket in the upper atmosphere. The analysis given allows us to value the passband of the upper sound channel, and the band in which possible registration of the wave indignations are conditioned by earthquakes.
