An external calibration system for DBF receiver arrays at Ka-band
An external calibration system for DBF receiver arrays at Ka-band
In der vorliegenden Arbeit wird ein Online-Kalibrierverfahren mit an-Bord Sonden für DBF Empfangssysteme entwickelt. Das sogenannte externe Konzept ist nicht nur für die Kalibrierung der Kanalschwankungen entwickelt aber auch für die Kalibrierung der Kanal-schwankungen und –Kopplung erweitert. Die Anwendbarkeit des Kalibrierkonzepts ist durch Experimente in Labor demonstriert.
In this thesis an online calibration procedure with on-board probes for DBF receiver systems is developed. The so-called external concept is developed not only for calibration of only channel deviations but also extended for joint calibration of channel deviations and mutual coupling. The applicability of the proposed concept is demonstrated by experiments in laboratory.
