| Popis: | Acoustic waves are commonly used in the detection, localization and focusing fields. DORT, a French acronym for decomposition of time reversal operator, is a novel method in which active detection and focusing of acoustic waves using arrays of transceivers is performed. The DORT method extracts relevant information from collected data and forms a multistatic data matrix (MDM) that enables the detection and focusing of signals on scattering objects. In this paper, the parameters of the DORT method are studied and their effects on the focusing performance are investigated. In addition, a truncated MDM method, which achieves both time and storage saving over the full MDM method, is proposed. Index Terms — DORT method, multistatic data matrix, parameter effects, time reversal, truncation. 1. |
