Abstract

The invention relates to a measuring device and a measuring method for systematic error detection. The measuring device comprises a processing unit (32), a first antenna adapted to receive a first signal and a second antenna adapted to receive a second signal. The processing unit (32) comprises a baseline unit (321) adapted to determine a baseline variance of the first variable and / or the second variable. Furthermore, the processing unit (32) comprises a variance unit (322) adapted to determine the variance of the first variable and / or the second variable. The first variable and the second variable are at least initially derived from at least the first signal and the second signal, respectively. The processing unit (32) further comprises an error unit (324) adapted to determine whether a systematic error exists based on the baseline variance and the variance of the first variable and / or the second variable.

Description

technical field [0001] The invention relates to determining systematic errors in measurement signals of at least two antennas, especially in direction finding applications. Background technique [0002] When determining the direction of the source of a signal, ideally the signal travels directly from the signal source to the measurement device that determines the direction of the source. However, this ideal situation cannot always be met in practice. In practice, multipath propagation and other effects that lead to systematic errors can occur. This negatively affects the direction of determining the source. Significant errors in the direction of the determined source can be caused by the effects described above. [0003] International patent application WO 2014 / 135196 A1 has shown an efficient measuring device and an efficient method for direction finding. However, this measuring device and method suffers from the problems mentioned above. Contents of the invention ...
