AIRBORNE SYSTEMS AND METHOD FOR THE CHARACTERISATION AND MEASUREMENT OF RADIATING SYSTEMS OR ANTENNAS
US2020003817; FR3591412T3; DE3591412T3
This invention relates to an airborne system and method for the characterization and measurement of radiating systems or antennas, comprising: an aerial module including a unit for measuring electromagnetic emissions, which captures the electromagnetic field radiated by the radiating system or antenna, and a positioning and guiding system with an accuracy equal to or less than 3 cm; and a ground station including a processing unit for the electromagnetic emission measurements, which processes the measurements using a set of algorithms. <br> The invention also relates to a method for measuring and characterising radiating systems or antennas. <br> This invention is suitable for sectors that require antennas to be characterised and measured, such as radar and radio navigation facilities, terrestrial and satellite-based telecommunications systems, or terrestrial broadcasting facilities. Granted and validated in France and Germany.
The main advantages respect to other current technologies are: <br> - Regarding SSR antenna diagnostics: antenna operators do not need to stop operations to have their SSR systems diagnosed.<br> - Regarding BTS antenna diagnostics: significant cost reduction compared to traditional methods.<br> - Regarding 5G antenna diagnostics: ability to assess the performance of complex antennas, such as multibeam antennas, used in 5G deployment.<br> - Regarding primary radar diagnostics:<br> allows the diagnostic task to be executed while the antenna under analysis (AUT) continues its operations;<br> it reduces the effects of the operating primary radar on the accuracy of measurements and prevents damage to the equipment.<p>
Our experience in active and passive tele-detection allows us to generate useful information for various applications including critical antenna diagnostics and BTS antenna diagnostics. <p>
• SSR antenna diagnostics: obtaining radiation patterns.<br>
• BTS antenna diagnostics: obtaining radiation pattern and BTS antenna performance diagnostics.<br>
• Diagnosis of primary radars: obtaining radiation patterns, identifying potential faults and performing antenna calibration exclusively by means of near field (NF) measurements.<p>
