zPRIME

Uncompromising 4D Imaging Radar Designed for Physical AI and Next-Generation Robotics

zPRIME

Ultra-Performance 4D imaging radar

zPRIME is our flagship imaging radar, combining breakthrough angular resolution, long-range performance, dense 4D point clouds, and software-defined configurability in a production ready sensor. zPRIME 3.0 is designed for developers building the next generation of autonomous machines, robotics, and intelligent infrastructure.

zPRIME is more than a high-performance radar. Build on our third-generation digital beamforming architecture and SDIR platform, zPRIME gives developers control and unlocks flexibility of the radar configuration. Output behavior can be adapted to the application on a case-by-case basis.

With 0.35° static angular resolution, 20Hz output rate, and kilometer-class detection range, zPRIME 3.0 delivers the perception performance needed for demanding environments. One sensor family delivers both close-range object separation and long-range detection through rain, dust, fog, darkness, and camera-blinding conditions.

A waveform you can change

RF-FMCW modulation on a cascaded SDIR™ front end, with antenna and waveform modes selectable per application. Optimize a mode for point-cloud density, or for Doppler, or for maximum instrumented range, without new hardware and without a new part number.

Third-generation digital beam-forming

0.35° static horizontal resolution across the full 120° field of view, with ±0.05° angular accuracy. The array separates two targets sitting in the same range-Doppler cell, the case where conventional radar returns one blurred blob and a wrong answer.

Built for Physical AI and Modern Robotics Deployments

With Long-Range, Wide, and Ultra-Wide antenna configurations, and both PoE and T1 interfaces, zPRIME is built to support the diverse needs of modern robotics in one integrated product family.

zPRIME is part of the broader Zadar development platform.

RSP Core provides basic functionality, flexible radar operating modes, and industry-leading point cloud output. Every sensor includes RSP Core.

Interference treated as a design input

Null steering suppresses jammers and in-band interference from up to 20 nearby active radars while detection holds. Tested to ISO 17387. As radar density rises on public roads and in mine fleets, this stops being a specification and starts being the reason a system works.

Software & deployment

Same sensor. Three ways to build on it.

How much of the stack you own is your decision, not a consequence of which hardware you bought. Deploy zPRIME 3.0 as a standalone sensor, build your own perception layer on top of our toolboxes, or take the complete Zadar solution. The radar underneath is identical in all three — so changing your mind later costs you integration time, not a new part number.

01

Standalone sensor

Deploy zPRIME 3.0 as a standalone radar sensor.

02

RDP Developer

RDP Developer provides the data-processing toolboxes needed to evaluate and integrate radar perception into autonomous systems, designed and tuned to work with zPRIME's point clouds.

03

RSP Studio

RSP Studio gives advanced teams the ultimate control to configure, visualize, analyze, and optimize radar RF parameters and signal processing performance.

One platform under all three. Move between paths without re-qualifying hardware, re-running environmental testing, or changing your mounting, wiring, or SKU.

0.35° ANGLE SHOWN EXAGGERATED CONVENTIONAL ONE DETECTION zPRIME 3.0 — TWO TARGETS MEASURED ON REAL-WORLD TARGETS · SNR ≥ 5 dB · SAME RANGE-DOPPLER CELL

Resolution

Two targets, one range-Doppler cell, two answers.

Angular resolution is where most imaging radar quietly gives up. Two pedestrians walking together, a motorcyclist beside a truck, a pole in front of a wall — same range, same relative velocity, and a conventional radar merges them into a single detection your perception stack then has to guess about.

zPRIME 3.0 separates them at 0.35°, measured on real-world targets with SNR as low as 5 dB. Not a simulated figure, and not measured on isolated corner reflectors.

COVERAGE zPRIME 3.0 INTERFERER INTERFERER NULL STEERED 20 NEARBY ACTIVE RADARS 118 dB DYNAMIC RANGE ISO 17387 TESTED TO

Interference

Built for roads where everyone else has radar too.

Radar-on-radar interference used to be a lab curiosity. It isn't now — every new vehicle on the road adds transmitters, and mine sites and ports run dozens in a few hundred metres.

zPRIME 3.0 steers nulls toward interferers and keeps detecting through up to 20 nearby active radars, tested according to ISO 17387. 118 dB of dynamic range does the related job on the physics side: a human at 110 m still registers with a bus reflecting hard in the near field.

zPRIME 3.0 EDGE PROCESSING 4D POINT CLOUD OBJECT LIST RCS PER TARGET UDP + PROTOBUF YOUR STACK 20 Hz 50 ms FRAME TIME 50 Hz WHERE SUPPORTED PTP IEEE 1588 SYNC

Edge processing

Perception at the sensor, not three hops downstream.

The radar outputs a 4D point cloud, an object list, and RCS per target in real time, over UDP with Protobuf, at 20 Hz — up to 50 Hz where the application supports it. IEEE 1588 PTP timestamping and sync-frame triggering keep multi-sensor rigs coherent to the frame.

Less to move over the bus, less to compute centrally, and lower latency between something happening and your stack knowing about it.

Applications

Deployed on things that move, and things that watch.

  • ADAS and autonomous driving in cluttered outdoor environments
  • Mining, construction, and agricultural vehicles where dust defeats optical sensing
  • All-weather safety envelope around the vehicle
  • Radar SLAM and odometry when GNSS drops out

Software

The sensor ships complete. The stack goes as deep as you need.

Core is included with every zPRIME 3.0 and covers everything required to stream, configure, and integrate the radar. Plus adds the zVUE perception stack. Pro opens the SDIR™ architecture itself — waveform, RF control, and processing tuning in your hands. Plus and Pro are delivered through a paid engagement.
