We investigate the feasibility of using a known elastic target located near the seabed for the purpose of inferring characteristics of marine sediment. In the problem considered the object position and its burial depth are not known with precision. F

This paper addresses the nondestructive testing of platelike structural components that are widely used in aerospace, marine, and civil structures. The objective is not only to detect and localize possible defects, but to reconstruct a picture of the

This paper presents a method to calculate the bistatic response of an elastic object immersed in a fluid using its structural Green's function (in vacuo structural admittance matrix), calculated by placing the object in a spatially random noise field

An interposed coupling material between an ultrasonic transducer and the test medium can be present in various non-destructive inspections and structural health monitoring imaging applications. One example is the wedge medium often used to direct ult

Rail inspection is commonly carried out by ultrasonic techniques that involve a pitch-catch or pulse-echo scheme to detect internal flaws. This method is usually implemented by Rolling Search Units (RSUs) whose maximum test speed is ~ 20-30 mph. Thes

The focus of this paper is the estimation of the dynamic transfer function between two outputs of a linear system subjected to an uncontrolled and generally unknown excitation, and accounting for possible uncorrelated noise present at both outputs. S

The acoustic response of an object depends on the surrounding environment. We show here how to take advantage of a known elastic target located near the seabed to infer characteristics of marine sediment. The approach consists of several steps. First
