Antenna Array Calibration for a General Linear Transformation of the Array Manifold

Abstract EN

We consider the problem of calibrating an antenna array using received signals from either known or unknown directions.

A complex matrix is used to map the assumed array manifold to the true array manifold.

This matrix may be completely unstructured.

Algorithms are presented for joint estimation of this matrix and the directions-of-arrival, using data collected during multiple time intervals.
