In this paper, the DOA estimation is implemented by spatialfrequencyspectrum analysis.
本文从空间频谱分析的角度来实现这一估计。

Different scenes are analyzed in the power spectrumspatialfrequency domain, it can be shown that the power spectrum of most natural scenes is of invariability.
用功率谱的方法对任意景物在空间频域进行分析表明,功率谱对于自然景物具有一定的不变性。

And the intensity of single frequency of the entire spectrum is contributed from emissions with wide spatial and Angle ranges.
