30 Km Detecting Radius Uav Surveillance Radar

• Range depends on RCS (target size): detection distance falls quickly for small plastic drones (RCS ≪ 0.01 m²). Vendors usually publish range vs RCS curves — insist on those.

• Environment & height: elevated mast/tower and clear LOS improve range dramatically; urban clutter, vegetation and sea clutter reduce practical range.

• Sensor type & processing: modern C‑UAS radars use Doppler/MTI, clutter suppression and specialized DSP to find low‑slow‑small (LSS) targets — these improve small‑UAV detection but still have shorter ranges than for large aircraft.

Representative vendors & real claims

• Blighter (A400 series / AUDS integrations) — proven air‑security radars; vendor materials show detection of small consumer drones in the ~0.5–3.6 km band and larger aircraft out to ~10–20 km depending on target. Good reputation and field demos.

• Meteksan (Retinar FAR‑AD / PTR) — tactical/perimeter radars optimized for low‑altitude threats; published data shows mini/micro UAV detection typically up to ~3–5 km and larger targets further (Retinar datasheets / case studies).

• China OEM / Marketplace listings — many vendors advertise “30 km” systems (some claim 30 km detection) at much lower prices; these require careful vetting — performance and support vary widely. Typical Alibaba/Made‑in‑China listings show USD 20k–80k price windows for such advertised units.
