可以得到通道增益的估计.

Abstract

The problem of sensor gains estimation is studied in two-dimension(2-D) DOA estimation system with dual circular array.By dividing the array into linear sub-arrays

we can transform the problem into combined estimation of DOA and sensor gains in linear array system.Under the constraint of DOA angles and sensor gains in the signal subspace

the estimation of sensor gain can be obtained without any calibration source.
