Submarine Target Detection Based on Static Electrical Impedance Tomography

Electrical impedance tomography is a non-invasive, safe, portable imaging technique that enables images of electrical impedance to be reconstructed from voltages measured with an array of electrodes placed on the boundary. Typically, an image data set is collected as a series of many impedance measurements designed to sample as much of the volume as possible. The method, as a typical method for geological studies, is applied for submarine target detection. A method based on complete electrode model and singular-value-decomposition method is applied to reconstruct the conductivity distribution of the DOI. Some numerical results are presented with detailed discussions.
