  • Device for measuring, at a plurality of points, the microwave field diffracted by an object
    Patent number: 5128621
    Abstract: An arrangement for measuring, at a plurality of points, the microwave field diffracted by an object. A microwave radiation source illuminates an object. Electric doublet antennae loaded by diodes are disposed in line along the path of the radiation diffracted by the object. A guide structure, with coupling antennae, is disposed along the line of doublet antennae and collects the diffracted radiation. Electronic circuits control the whole so as to measure the diffracted field at the position of each doublet antenna.
