OverviewThe R&S®AREG800A automotive radar echo generator is a modular test instrument for generating realistic radar echoes across development, validation and production environments. It is harmonized with the R&S®QAT100 antenna array and supports ISAC testing in sub-6 GHz and FR2 bands.
Key facts- Generates multiple dynamic artificial objects with individual distance, RCS, radial velocity and azimuth
- Instantaneous bandwidth options up to 5 GHz depending on configuration
- Hybrid echo generation: analog for short distances <17 m, digital for larger distances; optional fully digital down to air gap for FMCW
- Built-in HiL coprocessor and interfaces for synchronizing multiple units
- Optimized configurations for EoL production testing and calibration
Features & benefits- Compatible with R&S®QAT100 advanced antenna array and classical mmW remote frontends
- Supports bench and validation testing with mmW frontends and shielded chambers
- Flexible baseband options: 1 GHz base, upgradeable to 2 GHz, 4 GHz and up to 5 GHz
- Hybrid analog/digital concept enables short artificial-object distances and high scenario density
- Intuitive touchscreen GUI, SCPI remote control, SCPI macro recorder and code generator for integration
Applications- Testing short-range high-resolution radar sensors for emergency braking systems
- Scenario generation and functional-safety testing for radar-based ADAS/AD
- Vehicle-in-the-loop (ViL) and hardware-in-the-loop (HiL) tests for certification and homologation
- 4D radar sensor production testing and calibration including EoL
- Research and development for integrated sensing and communications (ISAC)
