Microwave imaging equipment utilizing an array of antennas operated to collect electromagnetic field information for a material being imaged. Image processing method and apparatus use the discrete dipole approximation (DDA) and drastically reduce the time required to process the measured data and estimate the properties of the material. Prior to interrogating the material, interaction matrices are generated and stored for future DDA calculations. The interaction matrices relate to the interaction between the antennas, the operating frequency, the background medium, and the location of the discretizing dipoles. An initial guess of the material properties is made and the resultant field is estimated. These results are compared to the measured results and incremental changes in the material property are computed. The updated material properties are used to recalculate the field. Comparison of the field to the measured field and updating of the material properties continues until an end criterion is satisfied.

DETECTION SYSTEM AND METHOD OF DETECTING CORROSION UNDER AN OUTER PROTECTIVE LAYER

Incoherent millimetre wave, sub-millimetre wave and terahertz test signals are used to probe metal substrates that are covered by a protective coating or outer layer, such as paint or thermal insulation, obscuring direct assessment of the substrate. The incoherent test signals, which may be from a naturally occurring passive source (such as the sky) and/or from an active noise source, provide signal dispersion and angular variation of the test signals with respect to angular incidence to the substrate. Illumination of the substrate permits differentiation between un-corroded and corroded sections of the sample because reflectivity (and emissivity) from a metal-based substrate is heavily dependent on the surface resistivity which in turn is dependent on the corroded state. A detector/camera is arranged to pick up reflections from the substrate and an associated control system identifies regions of the sample that reflect the test signal illumination differently or otherwise indicate a variation from a reference value. The differences therefore signify the presence or lack of corrosion or, indeed, the presence of other abnormalities within or on the substrate. 1.
