Automotive Radar Interference Testing with dSPACE DARTS

We present a powerful and flexible approach to test radar interference in the automotive sector with our DARTS (dSPACE Automotive Radar Test System). Our method enables black-box testing of radar sensors (no internal radar details required) and is therefore ideal for validating interference behavior in realistic scenarios.
Key features:
• Simulation of radar interference through signal superposition
• Full E-band coverage (76–81 GHz) with DARTS 9040-G and DARTS 9040-GT
• Spectrum analysis at intermediate frequency (IF) level
• Optional signal injection via signal generators

Why radar interference testing is important
With the increasing number of vehicles equipped with radar, interference between radar sensors is becoming an ever-greater safety issue. Our test environment simulates realistic driving conditions to evaluate the robustness of the radar and ensure reliable target detection even in high-noise environments.
We support OEMs and suppliers in developing robust radar systems using advanced simulation and validation tools.

FAQ

*Q1: Why are radar sensors tested as black boxes?*
A1: Treating radar sensors as black boxes allows testing without needing proprietary internal details, making the method applicable to various radar types by any third party.

*Q2: What frequency range do automotive radars operate in?*
A2: Automotive radars typically operate in the E-band frequency range of 76 to 81 GHz.

*Q3: How does superimposing interference signals help in testing?*
A3: It simulates real-world conditions where interference signals come from the same direction as the radar target echo, challenging the radar’s interference mitigation capabilities.

*Q4: What advantages does digital code modulation offer?*
A4: Digital code modulation enhances a radar’s robustness against interference, reducing false targets and maintaining reliable detection even with noise.

*Q5: Can interference be tested without a physical interference radar?*
A5: Yes, interference can also be introduced via signal generators for controlled and repeatable testing conditions.
