    摘要： The inventive detection method identifies metallic structures 2 below a surface 3 with a scanning detector 1. The scanning detector has a pair of laterally offset detection coils 8, 9 and an excitation coil arrangement 31, 32 symmetrically arranged with respect to the detection coils 8, 9. A movement of the scanning detector 1 along a path on the surface 3 is determined with a movement sensor 26. A sinusoidal excitation current 33 is injected into the excitation coil arrangement 31, 32. A frequency of the sinusoidal excitation current 33 is switched among a set of frequencies which contains a first frequency in a coupling regime between 15 kHz and 30 kHz and a second frequency outside the coupling regime. Signal amplitude A and signal phase p of a signal 7 induced in the pair of detection coils 8, 9 is measured for several positions along the path by an electric sensor. A material composition of the metallic structure is determined based on the sign of a derivative of the phase p along the path. An amplitude ratio R for signals of the first frequency to signals of the second frequency is determined. A first parameterization is selected among a set of stored parameterizations of amplitude ratios and diameter 12 relations based on the determined material composition. A diameter 12 of the metallic structure 2 is determined based on the first parameterization and the determined amplitude ratio R. A second parameterization is selected among a set of stored parameterizations of amplitude and depth 11 relations based on the determined material composition and determined diameter 12. A depth 11 by which the metallic structure 2 is buried below the surface 3 is determined based on the second parameterization and the signal amplitude A. The material composition, diameter 12, and depth 11 are transmitted to a display 21 or to a transceiver 51.

    摘要： A towed system for underwater electromagnetic prospecting for use with a seaward vessel is provided. The towed system comprises a first portion, a second portion, and a tow cable. The first portion is located on the vessel and includes a controller and a power supply system. The second towed portion is for submersion in the water and transmits an electromagnetic waveform and receives a corresponding electromagnetic signal. The tow cable connects the first portion with the second portion. The tow cable includes at least a pair of suitable conductors for delivering to the second portion a power signal generated by the first portion and at least one optical fiber for carrying data communications between the first portion and the second portion. The transmitted and received signals are digitized and this information is sent digitally to the controller in the first portion.

    摘要： An implementation of systems, devices and methods for a sensor to find a hidden element behind a surface are provided. The sensor includes a housing with a radiant indicator in a bottom section of the housing. The radiant indicator is translucent and acts as another indication that the sensor is over the hidden element. The sensor also includes a light source, such as an LED, which lights the radiant indicator with a beam, as well as optionally projecting an image on the surface, for example, formed by the bottom section and a top section of the housing. The same light source may also be used to project a second beam to an indicator on the top section of the housing.

    摘要： Obscured feature detectors and methods of detecting obscured features are disclosed. An obscured feature detector can include a plurality of sensor plates. Each of the sensor plates can have an equivalent primary sensing field zone and a capacitance that varies based on the dielectric constant of the materials that compose the surrounding objects and the proximity of those objects. A sensing circuit is coupled to the sensor plates to measure the capacitances of the sensor plates. A controller is coupled to the sensing circuit to analyze the capacitances measured by the sensing circuit. One or a plurality of indicators are coupled to the controller, and can be selectively set to identify a location of an obscured feature behind a surface.
