Best Coastal Early Warning Radar

High detection & tracking capability — ability to detect small, fast, non‑cooperative surface vessels (e.g., rigid inflatable boats, kayaks, drones) in cluttered sea‑states. For example, the Blighter C400 series has extensive sea‑clutter filtering and Doppler processing to detect even very small craft. Blighter+1

All‑weather, 24/7 operation — must perform reliably in fog, rain, waves, extreme temperatures, salt corrosion etc. Example: the Terma SCANTER solutions deliver full automatic operation in all weather conditions. Terma+1

Wide area coverage / long range — ability to monitor large coastal zones or Exclusive Economic Zones (EEZs). Terma’s system claims up to ~96 nmi coverage.

Low false alarm rate & strong signal processing — sea gives heavy clutter and many false returns; advanced algorithms (sea‑clutter filter, Doppler processing) are critical. Blighter emphasises these.

Integration & sensor‑fusion readiness — should integrate with AIS, EO/IR cameras, C2 (Command & Control) systems, networks, export of track data, remote monitoring. Example: the ELTA EL/M‑2226 supports interoperability with EO/IR, AIS.

Scalability & modular deployment — ability to deploy fixed, mobile, off‑shore, shore‑based; modular increments for future expansion. The Thales CoastShield system emphasises modular, scalable architecture.
