Results:

Velocity at maximum echo intensity and maximum velocity:

The velocity at maximum echo intensity is shown in Fig. 7. The maximum velocity is the highest velocity in the spectrum, which is measured at a threshold. This threshold is a multiple of the noise floor as shown in Fig. 8.

Mean Velocity and Standard deviation:

The mean velocity is a weighted average of spectra lines. These spectra lines are part of an area which is defined by an upper and lower boundary. These boundaries are calculated dynamically and the corresponding velocities are the highest / lowest velocity of an echo signal which passes the threshold. The standard deviation is calculated with the mean velocity.

Maximum echo intensity and overall echo intensity:

The maximum echo intensity is the highest echo signal in the spectrum (see Fig. 10). The overall echo intensity is calculated by an integration of all echo signals in an area, defined by upper and lower boundaries for the threshold (see Fig. 11).
