Description

Station Coordinate Arrangement Design Device for Ultra Low Frequency Detection

The present invention relates to an apparatus for designing station position coordinate arrangement for ultra low frequency sensing.

An integrated seismic observation network system is in operation for the United Nations Comprehensive Test Ban Treaty System (CTBT).

As a result of nuclear tests or artificial blasting, shock waves are transmitted to the atmospheric layer as a medium through shock waves.

Sound waves propagating in the air can be measured by the sound pressure sensor, but since the energy is small, several sound pressure sensors can be installed in a specific area to estimate the propagation direction and speed of the sound source by superimposing signals using the spatial correlation of the sound pressure sensor. have.

The spatial correlation characteristics (Array Response Function (ARF)) differ according to the arrangement of the sound pressure sensor, and the resolution and accuracy of the analysis differ according to the array response function.

Array design is a very important process in the design of sound station.
