The Radar Research Group of the Budapest University of Technology and Economics has been developing a distributed passive radar system. Multilateration principle is used to locate uncooperative drones, by capturing radio traffic in the ISM bands. The proposed radar system should be integrated into a more complex reconnaissance scheme, where additional sensors (e.g. PTZ cameras, microphone arrays,…)...
The Radar Research Group of the Budapest University of Technology and Economics has been developing a distributed passive radar system. Multilateration principle is used to locate aircraft in the zone defined by the location of the receivers. The measurement principle challenges the conventional tracking algorithms, therefore a new solution was developed.
This paper presents how a developed multichannel vector network analyzer, combined with the near-field measurement method, can significantly increase the reliability of surveillance services to air traffic control, by providing a faster measurement potential of the radar antenna's radiation pattern. A systematic radiation pattern check is vital to maintain the expected radar performance and safe operation.
The Radar Research Group of the Budapest University of Technology and Economics has been developing a distributed passive radar system. Multilateration principle is used to locate aircraft in the zone defined by the location of the receivers. This position estimation method is based on accurate time measurement. The current system uses the signaling of the secondary surveillance radar, specifically...
