Abstract :
The problem of array signal processing under model errors is studied. A signal subspace constraint is used to obtain a simple way for computing a set of sensor gains and phases consistent with a given set of DOA angles. Then the issue of uniqueness of the set of sensor gains and phases and DOA angles is addressed
