3.15 RHI : Range Height Indicator
Figure 20 RHI Example Configuration
RHI is a full screen image showing the detailed cross-sectional structure of a storm, used for
identifying severe storms, hail and bright band.
In general, you schedule the associated
RHI task through a region of interest.
During RHI scanning, the antenna azimuth is fixed and the elevation is swept, typically from
near 0 ... 90° to create a vertical cross-section effect.
If your antenna permits, it is often useful to make an over-the-top
RHI task (elevations for
example -2 ... 182). This gives a picture covering 2 elevations at the opposite sides of the
antenna. Negative elevations are most useful in
RHI if you select the azimuth to the direction
of least beam blocking of the radar horizon.
