| 摘 要： | 本文研究了基于双圈圆阵的二维DOA估计系统中通道复增益的估计问题.通过将阵列分割成子阵的办法,将问题转化为线阵系统中信号方向角和通道增益的联合估计问题.运用信号子空间对信号DOA和通道增益的约束关系,在无校准源时,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. |
