The centroid of three most closely spaced intersections of constant-range loci is conventionally used as trilateration estimate without rigorous justification. In this paper, we address the quality of trilateration intersections through range scaling factors. Several triangle centres, including centroid, incentre, Lemoine point, and Fermat point, a...

As the Automatic Dependent Surveillance-Broadcast (ADS-B) system has gained wide acceptance, additional exploitations of the radioed satellite-based information are topics of current interest. One such opportunity includes the augmentation of the communication ADS-B signal with a random biphase modulation for concurrent use as a radar signal. This...

Rapidly increasing growth and demand in various Unmanned Aircraft Systems (UAS) have pushed governmental regulation development and numerous technology research activities toward integrating unmanned and manned aircraft into the same civil airspace. Safety of other airspace users is the primary concern; thus, with the introduction of UAS into the N...

Conference Paper
In this paper we present a new principle for localization of backscatter RFID tags. A new algorithm comparable to synthetic aperture radar on a non-uniform trajectory is proposed. The performance is verified with measurement data acquired by a multi sensor platform which comprises radar, imaging and RFID. The identified RFID transponder positions a...
Conference Paper
In this paper we present a multi sensor concept for localization and augmented-reality visualization of backscatter RFID tags. The sensor data of a camera and a RFID FMCW reader system are combined based on a synthetic aperture radar principle. The system enables the localization of tagged goods without the use of any installed infrastructure. We i...

... For collision avoidance, utilizing satellite-based radar for UASs has been studied in [92]. A modified Automatic Dependent Surveillance-Broadcast (ADS-B) system is used. ...
... For this reason, several strategies have been presented to improve the accuracy of the distance estimation and localization of the Multilateration method. For example, the authors in Ref. [49] discussed the properties of the centers of triangles and used them to improve the Trilateration algorithm to deal with extreme trilateration scenarios, such as the case of two intersections. Also, some approaches, such as [28,50], proposed to resize the circle to correct overestimation or underestimation of circle radii. ...
... Several studies on different approaches to securing the ADS-B communications have been conducted in the past decade [43], [2], [1], [44], [39], [45], [46]. Some promising directions for generic RF communication defenses are explored by the physical layer security (PLS) techniques that were used to secure beamforming [47], [48], [49]. ...
... The proposed Quasi-ADS-B uses 900 MHz XBee-Pro 900HP for data broadcasting, instead of 1090/978 MHz in TCAS II for air transportation systems in the developing phase. The system design will suit different CD&R algorithms in TCAS for traffic advisory (TA) and resolution advisory (RA) [3, 10, 12]. The UAV/CD&R Quasi-ADS-B transceiver is designed and implemented for flight tests using ultralight aircraft in a small confined airspace. ...
... Werden dabei Sender und Empfänger in Hardware nicht-kohärent betrieben, kann eine digitale Trägerrückgewinnung am Empfänger genutzt werden, um die Kohärenz in der Signalverarbeitung wiederherzustellen, wie in einer betreuten Masterarbeit gezeigt werden konnte [99,131]. Die Messdauer ist im gewählten Aufbau sehr hoch und nicht für eine kommerzielle Nutzung geeignet, kann jedoch durch das Verwenden eines mehrkanaligen Empfängers [131] [132] und speziell für die RFID-Lokalisierung in [133] beschrieben. Um eine mit einem Handlesegerät aufgespannte synthetische Apertur für die Lokalisierung verwenden zu können, muss die zeitabhängige Antennenposition über der Zeit gemessen werden. ...
... Other system impairments such as receiver noise, phase noise of the RF synthesizer, instabilities of the modulation, as well as phase and amplitude distortion of the antenna and the RF system were ignored. However, based on practical experience with CW radar based RFID localization [6,8,9,13,15], most of these distortions can be kept small by careful system design, so multipath propagation is very often the dominating cause for ranging errors. The channel inside a UHF RFID portal is a severe multipath environment, providing a challenge even for ultra-wideband localization, as will be shown below. ...
