Figure 18. Volume Coverage Pattern (VCP) 21 samples nine elevation angles in about six minutes. The lowest two angles apply split cut with legacy range unfolding, middle angles use Batch (B), and higher angles use Contiguous Doppler without range unfolding (CD/WO) mode.
The elevation angles are: 0.50, 1.45, 2.40, 3.35, 4.30, 6.00, 9.90, 14.6, and 19.5. The beamwidth is 0.95.
