Measuring signal parameter estimation under object and material investigation by means of pulse electromagnetic fields

摘要

Pulse electromagnetic sounding is one effective method for environment, object and material physicomechanical characteristics study. The investigated environment information is contained in response signals that represent a sequence of fading voltage pulses. Under investigation, the receiving converter is also affected by a number of random and regular noises of pulse and continuous character that cause a stochastic structure of the informative signal and do not allow one to determine its informative characteristics without special processing. The processing mode of the stochastic signals depends sufficiently on their mathematical model. For the problem of registered signal parameter estimation, its mathematical model may be presented in the form of a sequence combination of its homogeneous informative elements (momentary signal meanings, durations, etc.) that are random processes.
