1. An apparatus for determining the roll position of a spinning projectile with the aid of polarized electro-magnetic radiation, comprising a transmitter for emitting polarized radiation in a direction towards the projectile and a polarization-sensitive receiver diposed in the projectile for receiving the polarized radiation, said polarized radiation emitted from the transmitter having an asymmetric wave-form which is formed by superimposing at least two mutually phase-interlocked radiation components of the wavelength relationship of 2:

  • 1 and/or multiples thereof, and wherein said polarization-sensitive receiver includes a single receiver antenna.
