TECHNICAL FACILITIES FOR ENSURING SECURITY
In the recent years, the battlefield acoustic exploration acquires a new dimension. This is due to the fact that modern weapons have a significantly increased distance of defeat, but the intelligence cannot detect such weapons at a sufficiently distance. In this connection the purpose of the present study is to investigate the near acoustic field of 122 mm artillery system firing. The collected with advanced technology equipment raw data were analyzed with the harmonic and wavelet analysis tools.
