In combination with the FSW-K60C option for analyzing FM CW signals, the FSW high-end signal and spectrum analyzer from Rohde & Schwarz automatically performs realtime characterization of the chirp signals typical of automotive radar. The ARTS automotive radar target simulator supplements this test system by adding realistic target simulation. Rohde & Schwarz is now selling the ARTS turnkey radar target simulator from ITS and miro-sys.
The ARTS series allows users to simulate dynamic targets with variable distances, speeds and sizes for radar test scenarios. The digital target simulators work at the 77 GHz and 24 GHz frequencies with a bandwidth of 500 MHz. They are based on a digital concept and can be easily configured for various applications and sensor types. Depending on the configuration, up to four independent targets with different parameters can be displayed in realtime.
The combination of the ARTS and the FSW lets users capture all key parameters of the radar sensor with a single measurement. The data is evaluated automatically. This test configuration offers major advantages in the areas of development, production, quality assurance and approval. In the past, users had to resort to static simulations, for example based on optical delay lines. However, this method represents only one or two static targets with distance, but without speed or angle.
When developing radar sensor chipsets, users can now use the Rohde & Schwarz system to simulate a realistic scenario in the lab. For example, it is possible to simulate vehicles with different moving profiles or stress tests in different environments. As a result, developers can verify the signal processing algorithms of the sensor at an early stage.
