a transceiver including a first antenna;
a memory; and
a processor, communicatively coupled to the memory and the transceiver, configured to:
transmit, via the transceiver to a second apparatus, one or more first signals from a first plurality of antenna elements, of the first antenna, and one or more second signals from a second plurality of antenna elements, of the first antenna;
receive, via the transceiver, one or more first indications of a first linear offset of a first signal distinction line relative to a second antenna of the second apparatus, the first signal distinction line corresponding to a first transition between the one or more first signals and the one or more second signals as received by the second antenna; and
determine, based on the first linear offset, one or more compensation parameters for compensating for the first linear offset.
