Abstract. The principles and
techniques used to detect signals propagating in the atmosphere in the
infrasonic frequency band are described. Such signals can be generated by
various sources: ground and air explosions, objects moving with supersonic
speed in the atmosphere (aircrafts, rockets, fireballs, fragments of spent
stages of carrier rockets). A description is given of portable infrasound
monitoring stations, each of which includes 3 infrasonic microphones spaced
apart from each other. Each such station makes it possible to determine three
basic parameters of an infrasonic signal, which are subsequently used to solve
the location problem: arrival time of the infrasonic wave, backazimuth to the
source and the angle between wave vector and day surface. A description is
given of an acoustic detector used to extract useful signals against a noise
background. The detector is based on an algorithm similar to the detection algorithm
STA/LTA known in seismology. Examples of the operation of the acoustic detector
with data obtained during real measurements are given. The technology of
passive infrasound location is described, which is based on mathematical
modeling of propagation of infrasonic
waves, generated by objects moving along possible trajectories, comparing these
theoretical signals with real ones, registered by monitoring stations, and determination
of realized trajectories. Examples of experimental confirmation of the passive
infrasound location technology effectiveness for determining the places of
fragments of 1 and 2 stages of carrier rockets fall are given. It is shown that
use of the systems of infrasound location allows to reduce the estimated area
of search for the fallen fragments of launch vehicles, significantly reduce the
time and cost or their search and utilization, and thus, to reduce the level of
the negative impact of the rocket and space industry on the environment.
