### Apodization Function -- from Wolfram MathWorld

· An apodization function (also called a tapering function or window function) is a function used to smoothly bring a sampled signal down to zero at the edges of the sampled region. This suppresses leakage sidelobes which would otherwise be produced upon performing a discrete Fourier transform but the suppression is at the expense of widening the lines resulting in a decrease in the resolution.

### Dual apodization with cross‐correlation combined with

· To address this problem we recently proposed an enhanced algorithm for linear-array PAM by introducing dual apodization with the cross-correlation (DAX) method into TEA. But due to that the delay and sum beamformer used to create RX1 and RX2 is non-adaptive the remaining X-type artifacts cannot be completely suppressed yielding
