DEVICE FOR MEASURING EFFECTIVE SCATTERING CROSS-SECTION OF OBJECT Russian patent published in 2005 - IPC

FIELD: radio engineering.

SUBSTANCE: device for measuring effective scattering cross-section of radio-location objects has receiving-transmitting unit, registrar, stand mounted for rotation and provided with fixing unit which is used for mounting test object oriented in such a manner that normal to flat front of electromagnet wave radiated by receiving-transmitting unit belongs to preset plane of rotation of object. Precision inspection of measurement of angular diagram of effective scattering cross-section of objects provided due to the fact that radio-transparent envelope is rigidly fixed on the surface of object in parallel with preset plane of rotation of object. Radio-transparent envelope is made in form of thin straight cylinder of preset size. Cavity of envelope is partially filled with e4lectrically conducting liquid. Measured maximal level of effective scattering cross-section of main lobe of radio-transparent cylinder allows to find angle of inclination of plane of rotation of object.

EFFECT: improved precision of inspection.
