Terma Scanter 2202 May 2026

In the complex theatre of modern maritime surveillance, the difference between a successful mission and a catastrophic failure often rests on the ability to detect the undetectable. As asymmetric threats evolve—from high-speed drug-running go-fast boats to stealthy periscopes and floating improvised explosive devices (IEDs)—navies and coast guards require sensors that break the traditional trade-off between range and resolution. The Terma SCANTER 2202 emerges as a solution to this dilemma. As a solid-state, pulse-compression X-band radar, the SCANTER 2202 is not merely an incremental upgrade to legacy magnetron systems; it represents a paradigm shift in surface surveillance, offering unparalleled small-target detection in high-clutter environments.

The key to its clarity is . By modulating the transmitted pulse (e.g., with linear frequency modulation or "chirping") and compressing the return echo, the radar achieves the range resolution of a short pulse while retaining the energy of a long pulse. This process drastically improves the Signal-to-Noise Ratio (SNR), allowing the operator to distinguish a 2-meter rigid-hull inflatable boat (RHIB) from wave clutter at distances exceeding 20 nautical miles—a feat impossible for magnetron sets.

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. In the complex theatre of modern maritime surveillance,
