Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

通过斜投影对空间相干目标进行DOA估计，非相干信号通过MUSIC算法估计，然后斜投影估计相干信号DOA。(DOA estimation of spatially coherent targets is made by oblique projection, and the incoherent signals are estimated by MUSIC algorithm, and then the oblique projection is used to estimate the coherent signal DOA.)
