  • Method and arrangement for determining the angle of roll of a launchable rotating body which rotates in its paths
    Patent number: 6727843
    Abstract: The present invention concerns a method and an arrangement for determining the angle of roll of a launchable body (4) which rotates in its path. The launchable body (4) can consist of a rotating projectile, shell, guided missile or the like, launchable from a launching device (1). According to the invention the transmitter antenna (3) and receiver antenna (5) are each designed with their sweeping beams (6, 9) directed essentially towards each other. By detecting the time the two beams (6, 9) coincide and the signal strength received in the receiver antenna, the angle of roll of the launchable body can be determined.
