Arralis has released an E-Band automotive radar, branded Corvus, and says it is working with leading automotive OEMs and seeking additional customers who wish to evaluate the system.

According to the company, the Corvus radar’s performance is better than other systems in the automotive marketplace, specifically detection range, elevation resolution and scan area. Monopulse is applied in both the azimuth and elevation planes to resolve the target’s angle within beams.

Corvus can detect multiple 3D targets up to 300 m over a ±45 degree azimuth angle and ±7 degree elevation angle. The system will detect a 0 dBm² target at 300 m, such as a fast approaching motorbike.

The radar uses a patented analog beamforming technique and Arralis’ MMIC portfolio, which is fabricated on a 0.1 μm GaAs PHEMT process to achieve the best noise figure and output power.

“Our extensive experience with all aspects of mmWave system design, from MMICs to beamforming and from antenna design to system integration, has enabled us to meet a demanding specification. To achieve a higher level of vehicle autonomy, the detection of targets at greater distances and in unfavorable weather conditions is essential. We see the Corvus Radar as essential to enabling safe operation of autonomous vehicles in the most challenging environments.” — Peter Ludlow, principal engineer, Arralis

Based in Limerick, Ireland, Arralis develops MMICs, packaged components, antennas and integrated front-ends for radar and communications systems.
