Abstract
A method for dynamically verifying a multiple beam antenna placed on a craft including a device for determining the position and course of the craft and a transmitter that via the antenna can emit pulsed signals. At least two transponders are placed in different directions round a measuring area with each transponder receiving a pulsed signal of at least one frequency, different for the different transponders, from the antenna. The transponders are adapted to send, after receiving the pulsed signal, a corresponding pulsed signal to the measuring station in such a manner that the transponder sending the signal can be determined at the measuring station which evaluates how well the antenna has managed to direct the radiated energy in the desired directions.
