阵列通道复增益盲估计

在阵列接收机各通道增益和相位不一致时，基于模型的超分辨波达方向估计性能大大下降。在已知２个信号的波达方向差的条件下，提出一种基于四阶累量进行盲信号处理的新算法。在方法中首先求出阵列流形，然后利用搜索法估计阵列通道复增益矩阵。

Blind Estimating of Complex Gains of Array Sensors

The performance of high-resolution estimation for DOA based on signals model will severely decrease with sensor gain and phase uncertainties. Assuming that the difference of DOAs of two signals is known, a new algorithm using fourth order cumulant is presented for blind signal processing. First the array manifold is estimated, then complex gains matrix is calculated by searching procedure.
