| 摘要 |
The present invention relates to an apparatus for determining the roll position of a spinning projectile (1), missile or the like by means of polarized electromagnetic radiation. The apparatus comprises a transmitter (2) for emitting polarized radiation in a direction towards the projectile and a polarization-sensitive receiver (3) disposed in the projectile or vice versa. The polarized radiation comprises at least two mutually phase-interlocked radiation components of the wavelength relationship of 2:1 and/or multiples thereof. |
