US digital-radar specialist. 2024 launch of the S81 mass-market 4D imaging radar using Digital Code Modulation (DCM) — interference-immune, single-chip, supporting up to 96 MIMO channels with High Contrast Resolution. May 2024 partnership with HASCO ADAS for production-vehicle integration. Like Arbe, the relevance is the substrate; defence-product applications follow. No C-UAS product yet.
