4. Select the maximum height and the horizontal width of the cross section in km and
enter them in Height Width .
There is no need to be exact, use the range and azimuth marks that are on the display
to estimate the horizontal width.
In the example, the height is 10 km (0.6 mi) and the width is 45 km (28.0 mi).
5. In Angle , select the orientation angle in degrees.
In the example, the angle is 50°. The angle that you select determines the end of the
cross section slice that is displayed on the right side of the display. An angle of 50°
displays as follows:
Left Side Right Side
23° end 50° end
To reverse the ends in the output display, select an angle of 50° + 180° = 230°.
6. In XZ Smoother , set the X and Z smoothing length scales independently.
Because of the interpolation performed in constructing the cross section product,
the output displays usually require little, if any, smoothing.
In the final output display, the zero point of the horizontal range scale corresponds to
the point on the cross section closest to the radar. This is also shown schematically in
the example.
This means that if you select a line that goes through the radar (which is allowed to
make a pseudo
RHI ), the 0 point is at the radar, so the horizontal distance equals the
radar range.
