Arbe’s patented 4D imaging radar leverages proprietary chipset technology to offer unparalleled performance over a virtual array of thousands of channels while optimizing cost and power consumption. Enhanced FMCW technology enables Arbe radar to transmit and receive signals from multiple antennas. By converting information from time to frequency domains (FFT), Arbe provides a 4D image with unparalleled element density in high azimuth and elevation resolution while simultaneously sensing the environment at a long range and to an extremely wide field of view.
Arbe is able to reduce side lobe occurrence levels close to zero, resolve range-doppler ambiguities, and avoid interference from other radars.
Arbe’s Phoenix radar supports more than 2000 virtual channels, tracking hundreds of objects simultaneously in a wide field of view at long-range with 30 frames per second of full scan.
This technological advancement has infused radar, the most dependable of sensing technologies, with ultra high-resolution functionalities to sense the environment in four dimensions: distance, height, depth and speed, effectively repositioning radar from a supportive role, to the backbone of the sensor suite.
Arbe proprietary technology leverages a physical resolution 2-10 times higher than alternative solutions which rely on synthetic or statistical resolution enhancement methods such as super resolution.
Due to use of high physical resolution, Phoenix remains effective in low SNR (signal to noise ratio) and multiple-object scenarios, which is when alternative methods fail. While Phoenix uses super resolution to accurately analyze object boundaries. It does not rely on this technique to generate a high- quality image.
The inability to distinguish threats from false alarms is a leading cause of autonomous vehicle accidents. False alarms trigger radar to report phantom objects, which in turn result in both false positives and false negatives.
Arbe’s FMCW enhancement, superior channel separation, and advanced post-processing reduce false alarms with close to zero instances of phantom objects, eliminating both false positive and false negative scenarios.
More vehicles equipped with radar sensors are released every year, some with as many as eight systems. Many of these radars are transmitting chirps on the same frequency bands, a reality that leads to signal mixing and increased collision rates. The more condensed the traffic, the higher the risk of mutual interference.
Arbe’s patented FMCW innovation actively avoids and mitigates other chirp transmitter interference, keeping channels clear to correctly track objects and ensure the road ahead is safe for drivers, passengers and pedestrians.
Arbe’s proprietary chipset utilizes the 22nm FDX full CMOS RF process, the most advanced RF process in the industry. This allows Phoenix to optimize required power per channel while dramatically reducing silicon size and related cost. Arbe leverages this efficiency to increase the number of RF chipset channels to provide higher performance at price points competitive with less advanced alternative solutions.
Due to its very high resolution level, Phoenix is an ideal solution for advanced localization and environment mapping.
Arbe affords customers the ability to add their own tracking, classification and localization algorithms. Alternatively, customers can leverage Arbe’s advanced AI based SLAM to identify and track objects, differentiate dynamic objects from their surroundings, predict multiple object trajectory, and conduct sensor fusion with camera and parallel systems.
