Advantages
Signal to noise is improved in a stilling well.
• Signal strength is extremely high over the entire measurement range since no beam
spreading losses can occur in the stilling well.
• Material surfaces that would reflect poorly without the stilling well can be measured
reliably within the stilling well.
Example
The following example shows two echo profiles, both from a 25GHz radar device with a
2" horn antenna. The pink profile shows the use of a 2" diameter stilling well, and the
blue profile represents open space. The following observations can be made about the
stilling well profile:
• The echo from the target is significantly larger.
• Multiple echoes are larger and continue for a longer time. This is not a problem, as
the first echo algorithm component of the Process Intelligence signal processing will
select the first echo.
