用七元线形天线阵（ULA）
已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个
源信号,假设它们的频率：0.015, 0.05, 0.02, 0.035
四个源信号的方向分别为：pi/4 pi/3 pi/6 3pi/4
求：
1）在不加入噪声的情况下,画出传统波束形成法、Bartlett波束
形成法、Capon波束形成法的空间谱图；
2）在加入高斯白噪声的情况下,假设信噪比为10dB，画出传统波束
形成法、Bartlett波束形成法、Capon波束形成法的空间谱图。(7-element linear antenna array (ULA)
Known: the signal center wavelength is 2, the antenna element spacing of 1 m, the number of snapshots for 2000, the air there are four
Source signal, assuming that their frequency: 0.015, 0.05, 0.02, 0.035
The direction of the four source signals: pi/4 pi/3 pi/6 3pi/4
Requirements:
1) not to join the noise, to draw the traditional beam-forming method, Bartlett, beam
Formation method, Capon beamforming method of the space spectrum
2) by adding Gaussian white noise, assuming that the SNR is 10dB, to draw the traditional beam
Formation method, Bartlett, beamforming, Capon beamforming method of the space spectrum.)
