Abstract
Method and systems for non-destructive testing of a gas or liquid filled object at atmospheric pressure or high pressure. The method includes steps of: providing an acoustic pulse reflectometry (APR) system having a wideband transmitter, a pressure sensor and a short mixed wave tube, performing at least one calibration to obtain at least one calibration parameter; attaching the object to the APR system and performing a measurement to obtain an object test result and processing the object test result and the at least one calibration parameter to obtain an object impulse response that reflects a status of the object.
