% 调零算法对幅相一致性的要求较高，且 AD9361 多片同步的精度随机性较大，因此需要对
% AD9361 多片同步误差进行精细校准。采用收发扩频码的方式在校准过程中对两片 AD9361
% 的两个接收通道进行幅相测量，在接收端使用加法器进行非相干相关峰累积，累积 N 个
% 符号后出峰，根据相关峰的高度差和相位差，在接收端对信号的幅度和相位进行补偿。

% Beamforming with phased array derives signal characteristics from phase
% differences between sensors. Therefore the amplitude-phase consistence is
% vital to phased systems.
%
% The script analyzes the amp-phase relations of ILA captured data, the format
% of which is square-shaped pseudorandorm bit sequence. Each channel is
% processed seperately with different frequency shifts and different optimum
% sampling points. The estimation of amplitude and phase are based on
% acculumated correlation peaks.
