To appreciate the SCANTER 2202, one must first understand its core technological departure from conventional radars. Traditional marine radars utilize magnetron transmitters, which emit high-power, short pulses. While effective for large targets, these systems struggle with small objects in rough seas or rain due to their fixed pulse length and limited dynamic range. The SCANTER 2202, by contrast, employs a solid-state transmitter using Gallium Nitride (GaN) technology. This allows the system to operate with extremely long pulses at lower peak power but high average power.
Beyond raw detection, the SCANTER 2202 is designed as a network-centric asset. It operates on the principle of "silent surveillance." Unlike traditional radars that emit continuously and betray the ship’s position, the solid-state architecture of the 2202 allows for Low Probability of Intercept (LPI) features. By spreading the transmitted energy across a wide bandwidth or using frequency agility, the radar is difficult for enemy Electronic Support Measures (ESM) to detect. Terma Scanter 2202
Terma’s system utilizes Doppler processing to analyze the velocity of returns. While waves and rain move with the wind, a maneuvering vessel has a distinct velocity vector. The SCANTER 2202 color-codes this information: stationary clutter appears in one hue, while moving targets stand out in another. Consequently, a semi-submerged narcotics submarine or a periscope generating minimal wake no longer hides in the "sea return." This capability makes the system invaluable for Exclusive Economic Zone (EEZ) patrol, counter-piracy operations, and naval base force protection. To appreciate the SCANTER 2202, one must first
