ARS548
Agency lineAUMOVIO’s ARS 548 RDI is a 77 GHz long-range radar with azimuth and elevation, a 0.22 m range resolution, and RDI over automotive Ethernet. Standard detection is 300 m. Anything beyond that is a customer configuration.

AUMOVIO Engineering Solutions offers ARS 548 RDI as an industrial long-range radar. Lodda supplies it on the agency line.
The sensor measures distance, Doppler speed, azimuth, and elevation in one cycle, using pulse compression. AUMOVIO describes a scan of 20 times per second, and the datasheet puts a full-field cycle at about 50 ms (about 70 ms for a rear measurement, 100 ms at standstill). The antenna count on the datasheet is 12 transmit by 16 receive, 192 virtual channels.
The range to quote as standard is 0.2–300 m, for natural targets. The product page also says a customer can extend the configuration toward 1,500 m, and the datasheet table lists an extended band of 301–1,514 m. That extension is conditional. Distance accuracy is ±0.15 m and depends on ego speed.
Azimuth is processed to ±60°, with ±50° on the object and RDI output. Elevation runs from about ±4° at 300 m to about ±14° inside 100 m. The interface is BroadR-Reach Ethernet at 100 Mbit/s. Supply is +8.5–17 V DC, and power is about 18 W typical, about 23 W maximum. Lodda supplies the sensor on the agency line.

Notes
- 1.300 m is the standard detection range in the datasheet narrative and the short description. Configuration beyond 300 m, up to the 301–1,514 m table and the “up to 1,500 m” product-page wording, is a customer setting and remains condition-dependent.
- 2.Distance accuracy of ±0.15 m depends on ego speed. The datasheet notes thresholds around 115 / 110 km/h.
- 3.The standard sensor is 76–77 GHz. The manufacturer describes a special case, SC1, at 80 GHz for China infrastructure. SC1 is a different build from the standard unit on this page.
- 4.Power and ingress are manufacturer datasheet statements, not Lodda certifications.
