zPRIME 3.0
Ultra-performance 4D software-defined imaging radar for physical AI, robotics and intelligent infrastructure
Overview
zPRIME 3.0 is Zadar's flagship 76–81 GHz cascaded imaging radar, built on a third-generation digital beamforming architecture and the SDIR (Software-Defined Imaging Radar) platform. It combines 0.35° static angular resolution, kilometer-class detection range and dense 4D point clouds in a production-ready, IP68-sealed sensor.
Output behavior is configurable per application. One sensor family covers close-range object separation and long-range detection through rain, dust, fog, darkness and camera-blinding conditions, with three antenna options and 1000BASE-T1, CAN and CAN-FD interfaces.
Features
- 0.35° static angular resolution, ±0.05° angular accuracy
- >1,000 m truck detection with the long-range antenna
- 20 Hz frame rate (up to 50 Hz on request)
- 118 dB dynamic range; null steering against up to 20 nearby active radars, tested to ISO 17387
- IEEE 1588 PTP timestamping and sync frame trigger
- IP68 (2 m), −40 °C to +85 °C operating temperature
- zPRIME 3.0 radar sensor (selected antenna configuration)
- RJ45 and PoE converter
- RSP Core software: 4D point cloud output with web visualizer
- HTTP configuration API and UDP radar data API
- SDKs for C++, Python, ROS 1 and ROS 2
- Ethernet firmware updates
- RSP Core: Streaming, configuration and integration: 4D point cloud, PTP time sync, firmware updates.
- zVUE (Plus): Camera-radar and GPS fusion, radar odometry, clustering, classification, multi-object tracking, online calibration. Delivered through a paid engagement.
- zSDIR (Pro): Custom waveform and RF control, custom processing tuning and full SDIR architecture access. Delivered through a paid engagement.
