A Velocity Dealiasing Scheme Based on Minimization of Velocity Differences between Regions

Figure 4

The behavior of the dealiasing in a region illustrated within a hypothetical azimuth-range sector: (a) the raw velocity, (b) the gradient corresponding to the raw velocity, (c) the dealiased velocity under Hypothesis 1, (d) the dealiased velocity under Hypothesis 2. Gray points indicate invalid data. Blue polygons in (a) mark the segmented subregions. Red rectangles in (a) and (b) denote the couples of points with abnormal gradient. Green polygons in (c) and (d) mark the dealiased subregions under different hypothesizes, respectively.
