In this paper, we propose a novel spatial filter based on the array-gain constrained minimum-norm filter, which is a modified version of the minimum-norm filter. The proposed method is designed to estimate the theoretical form of the measurement covariance matrix through recursively updating the gram matrix. The method is able to provide three-dimensional volume reconstruction with a spatial resolution considerably higher than that of existing minimum-norm-based methods.

Nonetheless, the method is free of the above-mentioned weaknesses occurring with adaptive spatial filters, because it does not use the sample covariance matrix. The method is also robust to the source correlation, and this robustness can be seen in our computer simulation as well as in our experiments using auditory-evoked MEG data.

Topic: Signal proccessing. Conclusion: The RMVB can be substituted for conventional beamformers, especially in applications where source imaging is performed off-line, and computational speed and complexity are not of major concern.
Significance: A high-quality source imaging can be utilized in various applications, such as determining the epileptogenic zone in medically intractable epilepsy patients or estimating the time course of activity, which is a required step for computing the functional connectivity of brain networks.
