Six-Port Error Propagation

摘要

In this contribution the various influences ont he accuracy of a ner range precision radar are described. The front-end is a monstatic design operatign at 34-36.2 GHz. The hardware configuration enables different modes of operation including FM-CW and interferometric modes. To achieve a highly accurate distance measurement, attention must be paid to various error sources. Due to the use of a six-port it is rather complicated to determine the corresponding error propagation. In the following the results of investigations on how to achieve an exceptional accuracy of +-0.1 mm are described.
