Research On Recognition And Extraction Method Of Target Object Characteristic Parameters Based On EMT

Identify and extract the characteristic parameters of objects by considering thesubstance structure and the relationship between the distribution of electrical conductivityand magnetic permeability at different frequencies. Develop an effective extraction andcharacteristic parameters fusion method. It is important to apply it to industrial inspectionand flaw detection.The subject combines theoretical analysis, computer simulation and experimentalmethod to implement. Explore various features of electromagnetic phenomena in EMT anddevelop effective extraction and fusion method that be able to reproduce the variousfeatures for target simultaneously according to test and simulation data.Research the EMT basic theoretical foundation of the system, including the basis ofelectromagnetism and mathematical, on the basis of electromagnetic sensing technologydocuments.Take advantage of the data acquisition principle and the outstanding graphicalprogramming LabVIEW platform to complete the EMT system of data acquisition andanalysis against the EMT system characteristics.According to the data acquisition technology derive multi-sensor data fusion methodand take advantage of it achieving corresponding results.Make detection for the spatial resolution of the sensor array and a comparison test ofthree common image reconstruction algorithms.
