频域波束成形算法，适用于所有一维和二维阵列的波束成形计算。对于采样时间较短的信号，采用了2次分段，对于采样时间足够的信号则只需要1次分段计算。计算结果包含成像图结果和各扫描点处的频谱结果(Frequency domain beamforming algorithm, applicable to all one-dimensional and two-dimensional array beam forming calculations. For shorter sampling signal, using a second segment, the sampling time sufficient signal need only 1 segment calculations. Calculation results include the results of spectral imaging of the results of each scan point)

hai this is useful for wavelet programming

it much easier to vary the parameters and see the results, but the underlying mathematical principles are unchanged. It shows that using polynomials of even modest degree to predict the future by extrapolating data is a risky business.
