| Abstract: | The spectrum estimation of array signal is discussed. By applying the spatial smoothing technology to the spectrum of two-dimensional signal, the problem of the frequency-bearing super-resolution of coherent signals is solved. The results of the simulation show that this method is useful and convenient. |
