2.6Reducing Precipitation Clutter

The vertical beamwidth of the antenna is designed to see surface targets even when the ship is rolling. However, by this design the unit will also detect precipitation clutter (rain, snow, hail, etc.) in the same manner as normal targets. Precipitation clutter shows as random dots on the screen.

2.6.1Adjusting the A/C RAIN

When echoes from precipitation mask solid targets, adjust the A/C RAIN to split up these unwanted echoes into a speckled pattern, making recognition of solid targets easier.
