TRS 3033 (Triton S)

TRS 3033 (Triton S) is an S band air and surface surveillance radar for shipboard mounting, used for surveillance and target designation functions in the Thomson Naval Combat Systems. Specially developed for detection of small air targets (aircraft and missiles) in a heavy clutter environment, Triton S is a fully coherent, digital processing, pulse Doppler radar which includes an independent pulse compression and frequency-agile receiver for detection of surface targets. Triton S can detect 2 m² air target at 26.2 km. Its subclutter visibility is at least 50 dB.

The antenna is of the non-stabilised type with a broad elevation lobe to counteract the effects of ship motion. The transmitter comprises a traveling wave tube. The radar provides two video signals, an air surveillance video and a surface video, which can be used for display, target designation and track-while-scan processing.

Since the middle of 1990 this radar is no longer in production.
