Note:
- Radar data may vary over different terrains when the radar is out of its detection range. Please see Appendix 1 for more details.
- Range detection might be limited by terrains, pitch, a roll of aircraft, etc. The range accuracy above only indicates the step size of data from the radar itself.
- Based on mm-wave radar specs, a large angle of pitch and roll would bring errors for detection. Under the same measurement circumstance, a larger angle by aircraft brings more error.
- IP rate here only focuses on radar itself. This rating does not cover any cabling interface.

Installation Instructions
Mounting Requirements:
- The antenna should be perpendicular to the target that to be measured
- Keep antenna housing clean, and do not cover it.
- Keep any unexpected objects out of radar’s FoV (Field of View), otherwise, it might situate the radar’s signal
- No specific requirement for mount orientation
About Einstein
Our mission is to enable safer driving, flying, working, and living through
radar-based technology. We are in the business of improving safety and
protecting valuable assets through innovations in radar technology.
Einstein makes radar systems smarter, more affordable, and easier to deploy. We
offer complete solutions for autonomous drones, advanced driver-assistance
systems (ADAS), autonomous vehicles, and industrial sensing – incorporating a
combination of millimeter-wave (mmWave) radar, sensor fusion, and arAficial
intelligence (AI).
For years, cost, weight, and performance constraints have hindered the wider
adoption of radar. Einstein makes radar systems accessible to everyone by
overcoming these constraints. One recent innovation: we’ve developed the
world’s first UAV collision avoidance radar with 4D detection.
Radar systems and sensor data processing intelligence are keys to our
autonomous future. We offer deep scienAfic, mathematical and engineering
expertise along with a full spectrum portfolio (24GHz, 60GHZ, 76-81GHz) of
hardware and software to support our customers in developing highly customized
solutions with unmatched precision in unpredictable environments.
Our core team has more than a combined 100 years of experience in radar
research and development with deep knowledge gained through projects funded by
NASA, the U.S. NaAonal Science Foundation (NSF), the European Space Agency,
and others.
Other radar companies are at least two to three years behind Einstein.
Startups have been slow to market and are unable to produce at scale, while
established companies are slow to adopt the newest technological innovations.
Einstein products can be fully customized to specific application requirements,
have unmatched precision in ALL weather conditions and surface types, and are
a fraction of the price of compeAAve products.
