Latest Patents

One of Vachenauer's latest inventions is an airport-surveillance system designed to determine the position and identification of aircraft on the airfield. This system utilizes secondary radar and includes an interrogation station installed on the airfield. The interrogation signal is transmitted through a narrow, sharply focused beam of an antenna that scans the airfield. The system also features transponding stations installed in the aircraft, allowing for accurate identification and location of the aircraft. By employing a receiver with a sharply focused antenna beam, the system ensures that replies from the aircraft's transponder are received only when the interrogation and receiving antenna beams intersect. This innovative approach is particularly suitable for large airports.

Another significant patent is a circuit for the comparative vector measurement of radio signal pulses, specifically DME pulses. This circuit is designed to handle multiple receivers that receive pulses simultaneously, even when there are large level differences. Each receiver is equipped with a switching amplifier that adjusts amplification in discrete stages. The circuit measures the instantaneous amplitudes and phases of the measuring signals at a specific time common to all receivers, enhancing the accuracy of radio signal processing.
