Multiple Choice

What suppression should be used with heavy cloud cover and storms?

Heavy rain and storm clouds create a lot of clutter on radar, making real targets harder to see. The best choice is a rain suppression setting, which uses a filter designed to dampen the rapid, strong echoes produced by raindrops. This Rain option, often implemented as a Filter Time Constant (FTC) suppression, reduces weather clutter while preserving actual targets like ships, so you can still detect them in storms. Infrared mode would switch to an infrared imaging view if available, but it doesn’t affect radar echoes. A UV filter and a polarizing screen are optical accessories for cameras or displays and don’t change radar performance or suppress weather clutter.
