A method for electromagnetic imaging of containers receives uncalibrated first data corresponding to signals of a first plurality of different frequencies associated with an antenna array residing in a container having contents. The method estimates of a second data based on a computer model and simulation of signals of a second plurality of different frequencies associated with the antenna array, the second plurality of different frequencies including a subset of the first plurality of different frequencies. The method compares magnitudes, without corresponding phase comparisons, of the first and second data at each frequency of the second plurality of different frequencies. The method updates the second data based on the comparing. The method provides information about the contents within the container based on the updated second data.

A image processing apparatus (20) includes at least an acquisition unit (210), a processing unit (220), and an image generation unit (230). The acquisition unit (210) acquires an intermediate frequency signal from an irradiation apparatus (10). The processing unit (220) generates three-dimensional positional information about a subject by processing the intermediate frequency signal. The image generation unit (230) generates at least a first two-dimensional image and a second two-dimensional image, and displays the two-dimensional images on a display apparatus (30). The first two-dimensional image is, for example, an image when viewed from a direction in which the subject moves, and the second two-dimensional image is, for example, an image when viewed from an opposite direction.

A long-term in-situ observation device for the deep sea bottom supported engineering geological environment is provided, including: a sediment acoustic probe, a sediment pore water pressure probe, a three-dimensional resistivity probe, a water observation instrument, a long-term observation power supply system, a probe hydraulic penetration system, a general control and data storage transmission system, an acoustic releaser, an underwater acoustic communication apparatus, and an instrument platform.

A soil imaging system having a work layer sensor disposed on an agricultural implement to generate an electromagnetic field through a soil area of interest as the agricultural implement traverses a field. A monitor in communication with the work layer sensor is adapted to generate a work layer image of the soil layer of interest based on the generated electromagnetic field. The work layer sensor may also generate a reference image by generating an electromagnetic field through undisturbed soil. The monitor may compare at least one characteristic of the reference image with at least one characteristic of the work layer image to generate a characterized image of the work layer of interest. The monitor may display operator feedback and may effect operational control of the agricultural implement based on the characterized image.
