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

Figure 6

The behavior of the dealiasing between interregions illustrated within a hypothetical azimuth-range sector. (a) The behavior of seeking reference points of subregion . (b) The behavior of seeking reference points of subregion after the dealiasing of the subregion . Gray points indicate invalid data., , and represent three isolated regions from the bottom to the top in the sector. Among them, the regions and have been checked by dealiasing between interregions, and the region is to be checked. The region can be segmented into two subregions and , as indicated by the blue rectangles. The blue line indicates that the two points can be directly connected, and the black dashed line indicates that the two points cannot be directly connected. The points marked in the green boxes in(a) are the reference points of the subregion ; the blue line connects the reference point to the nearest point in the subregion , and the red boxes mark several points that are not the reference points of the subregion . Similarly, the points marked in the green box in (b) are the reference points of the subregion ; the blue line connects the reference point to the nearest point in the subregion , and the red boxes mark several points that are not the reference points of the subregion .
