概述
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.

常见问题
Q1：为何将雷达传感器作为黑盒进行测试？
A1：将雷达传感器视为黑盒，即可在不需要了解其专属内部细节的情况下进行测试，从而使该方法适用于任何第三方的各种雷达类型。
Q2：汽车雷达的工作频率范围是多少？
A2：汽车雷达通常在76至81GHz的E波段频率范围内工作。
Q3：叠加干扰信号对测试有何帮助？
A3：它可仿真真实条件中干扰信号与雷达目标回波来自同一方向的情况，该情况对雷达的干扰抑制能力带来了挑战。
Q4：数字编码调制有哪些优势？
A4：数字编码调制有哪些优势？
Q5：不使用物理干扰雷达也可以对干扰进行测试吗？
A5：是的，还可以通过信号发生器引入干扰，以实现受控且可重复测试条件。
