Which statement best summarizes Powerful suppression?

• A. It suppresses weather clutter only
• B. It suppresses targets with fast relative motions, weak targets not painting consistently, and all targets when own ship is pitching and rolling
• C. It suppresses all echoes equally
• D. It has no effect on clutter

Answer: (B)

Powerful suppression is an aggressive radar processing mode that reduces clutter and unreliable echoes to keep only the most trustworthy returns. It works by damping echoes that are caused by rapid relative motion, which can make painting unreliable or false tracks appear, and by dropping weak, intermittently painting targets that are likely noise or clutter. It also suppresses all echoes if the platform itself is moving erratically (for example, when the ship is pitching and rolling), because the instability makes it hard to form a stable picture and avoid false targets. Because of this combination—removing fast-moving clutter, not-painting reliably weak targets, and all echoes during vessel motion—the described statement best captures what Powerful suppression does.
