Evaluation of the impact of antenna parameters on the performance of Six-port radar

The Six-port concept has been investigated in the last decades for numerous applications. Besides the use in network analyzers, communication transceivers and direction-of-arrival detectors the Six-port has also been applied in radar systems. Due to its excellent phase discrimination capability, Six-port radar features high range resolution and is therefore predestined for precise displacement and vibration measurements. In this paper, the influence of the antenna on both, accuracy and precision, of monostatic as well as bistatic Six-port radar systems will be studied.
