Description: Beamforming, an arrangement of five yuan uniform linear array, the array element spacing 15cm. Let alone the incident signal is sine wave, amplitude Acos (wt). Set velocity c = 1500m/s. The incident signal frequency f is 4k, 5k, 6k, find the three weighting coefficients beam pattern. 1) uniform weighting the beam pattern, the incident signal range-90 to 90, the amplitude normalization, the following figure. 2) array element weighting coefficient [1,2,4,2,1] 3) array element weighting coefficient [4,2,1,2,4]
