THE METHOD FOR DETECTING VOLUME CHANGES WITHIN THE OBSERVED LIMITED SPACE IS INDEPENDENT FROM THE PLACE OF THE ORIGIN OF THESE CHANGES WITHIN THIS SPACE.

摘要

1. A method for detecting stationary and unsteady volumetric changes within the observed limited space, regardless of the place of occurrence of these changes within the observed limited space, which consists in the fact that the space bounded by the acoustic section is probed with an acoustic signal, a reflected signal is received, this signal is stored until the object's position changes and comparing the signals before changing the position of the object and after changing the position of the object, characterized in that it is formed in the space bounded by the media section that is isotropic with respect to stationary or non-stationary changes under the conditions of propagation of an acoustic wave within this space limited by the media section, the acoustic field is measured, the amplitude, frequency and phase parameters of this field are measured at one or several arbitrary points of the observed space and by changing these parameters are judged on quantitative indicators of changes in the conditions of propagation of an acoustic wave in the observed spaces f, which are used to judge the quantitative indicators of volumetric changes regardless of their location within the observed space, namely, the formation of a region of sensitivity uniformly distributed over the entire observed space to both stationary and non-stationary disturbing factors, achieving independence of sensitivity from the place of occurrence of the disturbing factor within the observed space, including from the range to the receiving and radiating sides, including the independence of feeling
