Table 22. The model and its gain, width and attenuation parameters are illustrated in Figure

Gain: This parameter determines the magnitude of the central peak of the damped
cosine function.

Width: This parameter determines the width of the central lobe of the damped cosine
function. It approximately equals the width between the zero crossings of the function.

Attenuation: This parameter determines how fast the cosine wave is reduced to zero
magnitude, and therefore determines the height and width of the side lobes to either side
of the central lobe. Increased attenuation results in smaller side lobes. Note that the
asymmetric property means that the side lobes will each have a slightly different shape.
This attenuation parameter should not be confused with the medium attenuation that
determines how the RADAR amplitude diminishes as it propagates down the probe.
There are a total of 5 reflection models maintained by the transmitter to represent the types of
reflections that might be visible in an echo curve. These can be selected through the Reflection Model
pull-down selector under the Model tab shown in
