Automotive Radar Simulator Comes to High-End Spectrum Analyzer

The ARTS radar target simulator developed by ITS and miro-sys is now available from Rohde & Schwarz, to be used in combination with the company’s FSW signal and spectrum analyzer with the frequency-modulated continuous-wave (FMCW) chirp signals option

Radar is now frequently incorporated into automotive driver assistance systems (ADAS), and ARTS can be used to test automotive radar sensors during development and production. R&S’s FSW signal and spectrum analyzer performs real-time characterization of the chirp signals, while the ARTS automotive radar target simulator supplements this test solution by adding realistic target simulation. The combination of the ARTS and FSW lets users capture all key parameters of the radar sensor with a single measurement. Data is evaluated automatically.

With the ARTS series, users can simulate dynamic targets with variable distances, speeds, and sizes for radar test scenarios. The digital target simulators work at the 77- and 24-GHz frequencies at 500-MHz bandwidth. Based on a digital concept, they can be easily configured for various applications and sensor types. Depending on the configuration, up to four independent targets with different parameters are displayable in real time.

When developing radar sensor chipsets, users can now use the R&S solution to simulate a realistic scenario in the lab. For example, it’s 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.
