+%% File Header/文件说明
+%
+% 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.
