Radar shows random or grouped dots | NorthStar Navigation 8000I

42.5Radar overlay doesn't appear on the chart screen

It's possible that the charted area is outside the maximum range of the radar.

Try zooming in on the charted area.

42.6Radar shows random or grouped dots

Rain clutter often appears as random dots that can merge into badly-defined echoes on your Radar screen. The random signals are returned from rain, hail, sleet, or snow and can result in a confusing display; (see "Change the rain setting" page 134)

42.7Radar shows random signals in center

Sea clutter usually appears as confusing, random signals in the central area of the Radar screen. High waves will produce the maximum amount of sea clutter on the Radar screen.

You can optimize your radar display to reduce the effects of sea clutter; (see "Change the sea clutter setting" page 133)

42.8Radar shows different patterns on each sweep

Interference patterns always appear in a different place with each sweep. They can be randomly scattered bright dots or dotted lines that extend from the centre to the edge of your Radar screen, often producing a spiral effect. Generally, the stronger the interference, the wider the interference lines.

You can use the interference rejection feature to reduce interference patterns, and the width of the interference lines (see "Reduce interference from other radars" page 134).

42.9Radar shows multiple echoes off the same object

Multiple echoes off the same object are most likely to occur when you are close to a large target, and are usually only a temporary nuisance.

42.10Radar shows arcs and/or shadows

Side lobe patterns often appear as an arc or a broken arc. Shadows are blind spots.

If the radar is installed at a suitable height and in a suitable location on your vessel, side lobe patterns and shadows caused by obstructions such as funnels or masts will be minimized.

If you're having problems with these, you may need to relocate your radar. Consult the Installation Guide for your radar model for advice.
