This kind of beamformer can eliminate incoherentnoise when signals pass Wiener filter, then achieve a better speech-enhance effect by linear constraints minimum variance beamforming.
In order to suppress the coherent artigact noise, a method of image differentiation by means of monochromatic incoherent line source is described.
为了压抑相干噪声，本文采用单色非相干线光源进行图像微分。

Under the assumption of spatially-incoherent ambient noise, an analytical expression for the point-spread function of the imaging algorithm is derived.
