Abstract

The invention is concerned with a receiver device (10) for estimating a first time of arrival of a multi path signal. The invention is characterized in that the receiver device (10) comprises a polarimetric antenna array (12) and a controller device (11) comprising a first estimator (20), a signal decomposer (22), a time of arrival estimator (24) and a first time of arrival identifier (26); the polarimetric antenna array (12) is configured to receive the multi path signal; the first estimator (20) is configured to estimate a respective polarization and/or a respective angle of arrival of path components of the multi path signal received by the receiver device (10); the signal decomposer (22) is configured to decompose the multi path signal into isolated single path signals of the respective path components of the multi path signal; the time of arrival estimator (24) is configured to estimate a time of arrival of each of the isolated single path signals, and the identifier is configured to identify the minimum time of arrival.
