Here, the intensity of the radar echo is built up
per sweep (antenna rotations) so that sporadic
echoes that are not repeated at the same
geographical position are displayed with low
intensity.
The disadvantage of this filtering is that echoes
from fast boats can be filtered so that they do
not reach full intensity, but they will appear at
low intensity.
Speed direction
This function can be improved for fast echo in process setting by setting detection
to on, see below. If the echoes are small and moving fast, you can also use High
Speed RPM antenna, speedboat radar.
The echoes come with full force, and are dimmed on the subsequent sweeps
The echoes come in with full force and the intensity of the echoes is kept in 4-6
swipes and then dimmed down.
Radar echo is displayed, and noise is muted
