摘要： Embodiments of the invention are directed to a method of determining underground liquid (e.g., water) content. Embodiments of the method may include: receiving a first scan of an area at a first polarization, the first scan including first microwave reflections of the area and being from a first sensor for detecting microwave radiation reflections, the sensor being attached to an object located at least 50 meters above the area. Embodiments of the invention may include receiving at least one additional data. Embodiments of the method may further include filtering electromagnetic noise from the first scan using the at least one additional data. Embodiments of the method may further include identifying a first type of water source using the filtered first scan. Embodiments of the method may further include calculating the water content at locations in the area based on the identified first type of water sources. Embodiments of the invention may further include converting the calculated water content from reflection intensity levels to quantities of water capacity for the one or more scanned areas.

摘要： A sign of the landslide disaster is easily detected. A model learning unit (120) of an anomaly detection device (100) learns a relational expression between vibration strengths at frequencies based on a time series of frequency characteristics of a vibration strength detected during a learning period by a vibration sensor placed on a monitoring target. The anomaly detection unit (140) learns a relational expression between vibration strengths at frequencies based on a time series of frequency characteristics of a vibration strength detected during a new period by the vibration sensor. Then, the anomaly detection unit (140) determines whether or not there is an anomaly in the monitoring target based on a relational expression related to a new frequency, which is different from the relational expression learned during the learning period.

摘要： A GPS-based underwater cable positioning system for use in determining the shape and position of hydrophone streamers towed underwater behind survey vessels involved in marine seismic prospecting. The system includes a plurality of surface units towed behind the vessel. Each surface unit includes a GPS receiver to receive radio frequency GPS signals and to determine its positions. Each surface unit also has an acoustic transmitter to transmit an acoustic message signal representing its position and an optional time stamp into the water. Acoustic receiver units, attached spaced apart locations along one or more streamer cables, each include an acoustic receiver to receive the acoustic message signals from the surface units and to determine its position from the message signals. To augment the message signals from the surface units at locations distant from the surface units, acoustic transceiver units may be used. The acoustic transceiver units are attached to the streamer cables at ranges between the surface units and distant acoustic receiver units. The acoustic transceiver units each include an acoustic receiver that performs as the receivers in the acoustic receiver units and an acoustic transmitter to transmit acoustic message signals representing its position and an optional time stamp into the water to be received by the acoustic receiver units. In this way, the positions and shapes of towed streamer cables can be determined.

摘要： The invention provides a seismic transmitter source system which includes a floatation device that contains a plurality of air tight chambers in a serial connection. A separate one way check valve is placed between each adjacent pair of the chambers. Pressurized air is continuously supplied to an end chamber. The one-way check valves enable the air to pass to the remaining chambers in one direction. A transmitter subarray containing a plurality of spaced apart transmitters is suspended from the floatation device by means of severasl pivotly connected links. The front end of the transmitter array is connected to a point near the front end of the floatation device. During operation, the seismic transmitter source system is pulled from a tow point located at the front of the floatation device, pulling both the floatation device and the transmitter subarray in substantially a horizontal straight line position while maintaining the transmitter subarray at a near constant depth below the water surface.

摘要： A method of marine seismic investigation involves positioning or deploying at a predetermined point close to or within a multi-element seismic source array a calibration source which is an acoustic pressure wave point source which has a far-field seismic signature of broad bandwidth. The radiated pressure wave field of the calibration source (3) is weaker than that of the main source (2). The two sources are fired at separate instants within a predetermined time range, preferably with the calibration source (3) being fired about two seconds before the main source (2). The reflected response of the sub-surface strata is recorded and processed to generate seismic data. In one embodiment, the response is recorded with two hydrophone arrays - a short high-resolution array (4) and a conventional main array (5). The method can be used to determine the far-field signature of the main source array (2). It can also be used to obtain a high-resolution shallow seismic section simultaneously with a deep seismic section. Apparatus suitable for the method is described, and also a method of conducting an underwater seismic survey.

摘要： A system and a method may detect underground water or gas leakage. The method may include receiving a first scan of an area including an underground gas pipe at a first polarization, the first scan including first microwave reflections of the area at a wavelength range of 3.8 cm to 1.3 m; receiving additional data, filtering electromagnetic noise from the first scan using the additional data; creating a water roughness map based on typical roughness values of a set of types of water sources and the filtered first scan; identifying one or more water accumulations at one or more locations along the gas pipe using the water roughness map and the filtered first scan and calculating the water content at the one or more locations along the gas pipe based on the identified one or more water accumulations.
