ABSTRACT:
A method and apparatus for identifying the distribution of the dielectric constants in an object employ radiation emitted by a microwave transmitter directed at the object, which radiation is received by a microwave detector array. The dielectric constant distribution is calculated in a computer from the output signal of the detector array, and is represented on a monitor. The transmitted and scattered radiation is acquired by the array in a prescribed volume in terms of amplitude and phase. For this purpose, the array has a surface with detector elements thereon which is linearly displaceable in a direction toward the microwave transmitter in steps along a selected path. At each step, the incoming radiation is identified in terms of amplitude and phase at a plurality of measuring locations, the number of measuring locations corresponding to the number of individual detector elements within the array. This measuring phase is thereafter combined with a calibration phase for further processing.
