What is it about?
The radar sensor evaluates the reflection of its transmit signal at different objects (cars, persons, trees, etc.) to detect and track the surrounding environment. By the system described in this article we are recreating the effects the radar sensor faces while driving on a road in a laboratory or test rig.

Why is it important?
The radar sensor is an essential contribution to the perception capability of actual and future cars. The input generated by the sensors is used by drive assistance features in the car an input for their decision making process. To evaluate and test such features under defined conditions the car must be moved from the road to a test rig. Here the sensors of the where certain test are stimulated based on the desired test cases. The stimulation should be accomplished without moving or changing the operation or position of the considered sensors. Our radar target stimulation concept is able to cover this functionality
Perspectives
Modern advanced driver assistance systems (ADAS) are taking a increasingly important role to rise the level of comfort in our cars and avoid accidents. Only comprehensive testing of these features allows us to rely on these functionalities under the wide range of environmental conditions we face on the road. The more of these features are operating in parallel in a car the more comprehensive their testing will be. Hence, we urgently require a robust framework for these test under defined repeatable conditions.
