Doppler Radar Target Simulators
Automotive radar sensors play a vital role in the current development of autonomous driving. Their ability to detect objects even under adverse conditions makes them indispensable for environment-sensing tasks in autonomous vehicles. As their functional operation must be validated in-place, a fully integrated test system is required. Radar Target Simulators (RTS) are capable of executing end-of-line, over-the-air validation tests by looping back a received and afterward modified radar signal and have been incorporated into existing Vehicle-in-the-Loop (ViL) test beds before. However, the currently available ViL test beds and the RTS systems that they consist of lack the ability to generate authentic radar echoes with respect to their complexity. The paper at hand reviews the current development stage of the research as well as commercial ViL and RTS systems. Furthermore, the concept and implementation of a new test setup for the rapid prototyping and validation of ADAS functions is presented. This represents the first-ever integrated radar validation test system to comprise multiple angle-resolved radar target channels, each capable of generating multiple radar echoes. A measurement campaign that supports this claim has been conducted.

Stand-Alone Doppler Current Sensor
DCPS
The Doppler Current Profiler Sensor (DCPS) is a medium-range, 600kHz current profiler smart sensor. It offers high-quality ocean current measurements and is ideally suited for cabling directly to various systems or dataloggers via serial or AiCap bus. With its integrated compensation for tilting and movement, the sensor is commonly used to measure current from buoys and other moving platforms.The 5400/5400R version of the current sensor is 300m depth rated, the 5402/5402R version is 4500m depth rated, and the 5403/5403R version is 6000m depth rated and intended for commercial as well as research use. It comes with an integrated temperature sensor that can be calibrated on request.As an extension to the DCPS, we now offer the current profiler with an integrated pressure unit called the 5400P. This version enables acoustic wave measurements in addition to profiling currents. Ideal for small observatories, the DCPS sensor is the market's lowest-cost current and wave sensor.
