SYSTEM FOR DETERMINING THE ANGULAR SPIN POSITION OF AN OBJECT SPINNING ABOUT AN AXIS

摘要

The invention relates to a system for determining the angular spin position of an object (1) spinning about an axis The system thereto comprises means (7) for transmitting at least two superimposed phase-locked and polarised carrier waves to obtain the angular spin position. The system further comprises at least two loop antennas (10), connected to the object (1), and receiving means (13) for processing in combination the antennas-received signals.
