Continental ARS 408-21
The Continental ARS 408-21 Radar is preferred with the Baidu Apollo kit. It is fast, safe, reliable and cost-effective and produces real-time distance to object scanning. This radar has a built-in fail-safe that can detect a possible risk of collision (dependent on speed of vehicle) and display it automatically. It works through all weather conditions with a low-performance loss in extreme conditions. Costs are kept low by using Radar technology with less complex measuring principles, development and mass production in the automotive industry.
Features
- The ARS 408-21 provides both excellent measuring performance and reliable operation. This sensor provides real-time object information, such as distance, and is intended to be used for collision mitigation.
- Applicable at all weather conditions and performs well even in extreme situations.
- Self-diagnosing fail-safe operation.
- Produces quality targets, free of false positives, without the use of additional filters.
