Hello,
I have attached a paper about Planar Interferometer Arrays. Now I’m trying to understand this paper but something confuses me. I am very thankful if somebody can help me with it.

It seems to me that direction cosines and phase differences are 1:1 correspondent, that is, a phase difference can lead to a fixed direction cosine. Is it correct?By using multiple antenna-pairs in a suitable geometric configuration, it is a simple matter to ensure that the mapping from the set of possible direction cosine pairs onto the set of relative phase measurement vectors is one-to-one and therefore invertible by a doa estimation algorithm.

What is meant by „unmeasured integer portions of the relative phase measurements between all antennas pairs“? Does it have something to do with resolving ambiguities?Determining a unique source direction from a given relative phase measurement vector involves, at least implicitly, determining the unmeasured integer portions of the relative phase measurements between all antennas pairs.
