A subspace method for estimating sensor gains and phases
Victor C. Soon, Lang Tong, Yue Huang, R. Liu · IEEE Transactions on Signal Processing · 1994
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.>
