Promise of a Better Position

Abstract

I ndustrial automation today is an essential technology underlying our modern society. Advanced positioning and sensor feedback tasks in automation processes often require distance displacement detection, e.g., to measure and track the movement of robots. Furthermore, the detection of mechanical stress in complex industrial machinery through an accurate vibration analysis is often a task of major interest. Therefore, high-resolution distance measurements with short-and long-range positioning are important for a large number of sensing applications and can also be used as a precondition for vibrometer applications. Several automation technologies rely on high precision positioning sensors to track linear as well as rotational movements of various machinery. The tracked positioning information provided by the sensor interface determines the accuracy of the positioning system, thus the quality

Planar Directional Couplers and Filters

“…As outlined in the preceding sections, directional couplers make use of nonreflective terminations. These couplers are essential parts of scattering parameter testsets for homodyne (six-port) [41,69] and heterodyne vector network analyzer (VNA) architectures…”

Multiport Technology: The New Rise of an Old Concept

“…MULTIPORT FOR LOCALIZATION Multiport technology is not only capable for data transmission and network analysis, but can be also used for localization purposes [20]. Besides distance measurements, angle-of-arrival (AoA) and vibration analysis are also promising applications [21].…”

“…Values in the micrometer range for resolution can be obtained at Ka-band frequencies, with state-of-the-art analog to digital converters (ADC) [21]. Fig.…”

A 24 GHz Waveguide based Radar System using an Advanced Algorithm for I/Q Offset Cancelation

“…The radar technique of the realized radio frequency (RF) front end is based on the Six-Port principle, a special kind of continuous wave (CW) radar (Vinci et al, 2012). Due to nonidealities of integrated components and especially reflections, particularly at the transition between printed circuit board (PCB) and waveguide, the information signals have an interfering DC bias.…”
