Device and method for positioning of a moving object in a monitorable region using a stationary monitoring system and a transponder attached to the moving object. Furthermore, the monitoring system contains at least two sensor units and an analysis unit, which allow distance values (Dx) to be established using travel time measurement of ultrasound signals (US) and positioning to be performed therefrom.

Device and method for positioning

The interrogation device is used for identifying a target device. A transmitter is designed for transmitting a coded electromagnetic radiation. The target device has sensor means for detecting this radiation and for converting it into electrical signals, which are supplied to an evaluation unit, as well as transmitting means which, in accordance with decisions made by the evaluation unit, return messages to receiving means located inside or outside of the transmitter. The transmitter comprises a circuit with an oscillator and an antenna, which are designed to generate individual pulses, or short bursts of pulses in the giga-frequency range, which are chronologically modulated. A coded information signal is obtained from these pulses.

Interrogation and responder system for identifying a target

The simulation system is used in the course of firing exercises, in particular with a laser beam, for simulating conditions which would arise if actual ammunition were used. For identifying a responder device ( ), an interrogation device ( ) transmits a coded radiation, which is detected in the responder device and is converted into electrical signals, which are supplied to a central unit ( ) on the receiving end for transmitting identification messages back to the transmitting device in accordance with decisions made by this central unit ( ). The interrogation device generates laser radiation or electromagnetic pulses or pulse bursts containing information which is coded in such a way that the response pulses being sent back by the responder device to the interrogation device additionally enable a central unit ( ) on the transmitting end to calculate the distance between the interrogation device and the responder device.
