Known: the signal center wavelength is 2, the spacing of the antenna array is 1 meter, the quick number is 2000, and there are four in the air Source signals, let's say their frequency The directions of the four source signals are: O: 1) observe and calculate the eigenvalue of covariance matrix and characterize it without adding noise To illustrate 2) using the MUSIC algorithm, CAPON algorithm, ESPRIT algorithm in the following four cases, right The poda direction of the above four signal sources is estimated, and their space spectra are drawn. In the absence of noise, In the case of adding gaussian white noise, the SNR is assumed to be 10dB 3) when the range of SNR is -20db ~+ 20dB, the MUSIC algorithm is adopted respectively, CAPON calculates The method, ESPRIT algorithm, estimates the direction of the four signal sources and draws the poda side To the estimation error, the graph of the change of the signal-to-noise ratio
