Detection and Sensing of Mines, Explosive Objects, and Obscured Targets XXIII.
Down-looking ground penetrating radar (DLGPR) has been used extensively for buried target detection. Performance of a DLGPR is typically measured by calculating the probability of detection (PD) and the false alarm rate (FAR) against a target set in

Detection and Sensing of Mines, Explosive Objects, and Obscured Targets XXIII.
The U.S. Army RDECOM CERDEC Night Vision and Electronic Sensors Directorate (NVESD) Countermine Division has developed a program to investigate multiple sensor modalities to detect side-attack explosive hazards. Sensor modalities include vehicle-moun

Detection and Sensing of Mines, Explosive Objects, and Obscured Targets XIX.
Down-looking ground-penetrating radar (DLGPR) has been used extensively for buried target detection. For operational implementations, the sensor is used in direct-detection mode, where algorithms process data while the system moves down roadways. Dec

Numerical calculations of acoustic scattering may be based on either differential equations or on corresponding integral equations. The differential equations generate a sparse matrix problem involving (possibly implicitly) an M by M matrix. Integral

It is known that an elastic cylindrical lossless shell immersed in an acoustic fluid can guide acoustic energy longitudinally without attenuation. In fact, for the physical and geometric parameters within suitable ranges, different surface wave modes

The vibrational response of a circular cylindrical shell of a finite length in vacuum, excited by a point force of arbitrary orientation, is studied by using wave techniques and the state vector formalism. Because of the geometric symmetry, both the

A novel outdoor synthetic aperture acoustic (SAA) system consists of a microphone and loudspeaker traveling along a 6.3-meter rail system. This is an extension from a prior indoor laboratory measurement system in which selected targets were insonifie

The near‐field to far‐field projection procedure here introduced has the following novel features. (1) The measured near‐field samples do not need to belong to a separable coordinate surface. (2) The number of samples is, in principle, as small

For vehicle-mounted down-looking ground penetrating radar (DLGPR) systems, the largest response is typically due to the radar reflecting off the ground. Most DLGPR algorithms remove the ground bounce response as a first preprocessing step. The remain
