MTI stands for Moving Target Indication. What is its primary purpose on a shipboard radar?

• A. Moving Target Indication; to suppress stationary clutter so moving targets stand out on the display.
• B. Maritime Target Identification; to classify inbound vessels.
• C. Multi-Target Integration; to merge returns into a single track.
• D. Moving Target Imaging; to visualize movement patterns.

Answer: (A)

MTI uses Doppler processing to separate moving echoes from stationary clutter. On a ship’s radar, stationary reflections from waves, the sea surface, and fixed objects can fill the display and hide real targets. By suppressing these stationary returns, MTI makes moving targets stand out clearly, so the operator can detect and track them more reliably, even in rough sea conditions. This isn’t about identifying vessels, merging multiple targets into a single track, or producing a special visualization of movement patterns. Those functions are different tasks; MTI’s main job is to filter out the nonmoving clutter so moving targets are highlighted on the display.
