Rohde & Schwarz has expanded its automotive radar target simulator R&S AREG800A by introducing new options, including the R&S AREG-P, designed to create a seamless transition from R&D to production for automotive radar sensors. Whether used as a standalone solution or integrated with NOFFZ production test systems, the R&S AREG-P helps Tier 1 automotive radar suppliers boost throughput, reduce testing time, and optimize costs during end-of-line testing.
The transition of radar sensors from research and development to full-scale production is a critical process. Ensuring a smooth transition is essential for maintaining the performance, reliability, and durability standards established during the R&D phase. Any issues during this phase could affect the radar’s performance, potentially posing risks to vehicle safety and road users.
The R&S AREG-P, based on the advanced AREG800A radar target simulator, is specifically designed to address the complexities of production testing with its modular structure and highly configurable precision parameters. It consists of a base unit that can support up to three fully digital channels for independent simulation of objects, with each channel generating one object. The base unit can connect to three frontends, providing flexibility to adapt to various production environments. Additionally, with 5 GHz RF instantaneous bandwidth and analog IF output interfaces, the radar under test can be analyzed for EIRP using an R&S NRP8S(N) diode power sensor and bandwidth via an R&S FSV3007 signal and spectrum analyzer. This comprehensive setup ensures that production models meet the rigorous performance benchmarks established during R&D, ensuring quality assurance and regulatory compliance.
The R&S AREG-P offers several models, each catering to different production requirements:
- R&S AREG-P1: Known as the Radar Mini configuration, this model smoothly integrates the AREG’s radar test technology into production systems.
- R&S AREG-P2: The Radar Golden configuration allows simultaneous testing of two radars in two separate chambers during production using a single target simulator.
- R&S AREG-P3: The Radar Pro configuration eliminates the need for azimuth sweeps, reducing testing time.
- R&S AREG-P2+3: Also known as the Radar Golden-Pro configuration, this advanced solution eliminates both azimuth and elevation sweeps, further cutting down production testing time.
By leveraging the proven performance of the R&S AREG800A, these new options are optimized for future automotive radar production requirements. Additionally, the CATR (Compact Antenna Test Range) reflector technology is integrated into the production process, providing another benefit by allowing radar sensors to be tested under far-field conditions within a minimal test footprint. This technology has already demonstrated its efficacy in testing 4D radars and is poised for future radar antenna developments.
The AREG-P systems bring considerable business advantages, enhancing operational efficiency and profitability in automotive radar production. The modular design aids in distributing Capital Expenditure (CAPEX), while its high accuracy minimizes Operational Expenditure (OPEX) and Time to Market (TTM). Furthermore, the compact design not only saves space but also reduces CO2 emissions, promoting environmentally friendly testing environments. The flexibility and scalability of the system further contribute to reduced OPEX, enabling quick deployment and lower setup costs.
By ensuring a seamless transition of radar sensors from R&D to production, the R&S AREG-P reduces the risk of failure, improves First Pass Yield (FPY), and minimizes waste while increasing productivity. Key features like variable object distance, patented technologies such as airgap minimization for FMCW radar sensors, and vertical chambers with CATR are carried over from R&D to production, ensuring consistent performance.
Ludwig Mair, Business Development Manager for Radar at NOFFZ Technologies, remarked: “At NOFFZ, we are thrilled to collaborate with Rohde & Schwarz in integrating the R&S AREG-P into our test systems for end-of-line production. This partnership allows us to deliver an unmatched combination of performance, cost-efficiency, and environmental sustainability to our customers.”
In conclusion, the R&S AREG-P models provide a range of solutions tailored to meet the evolving needs of the automotive radar production sector, offering flexibility, accuracy, and efficiency to enhance production testing processes.
