Rohde & Schwarz verifies reference design for automotive radar sensor of NXP

Application for extremely short object distances

NXP Semiconductors has chosen the "R&S RTS" radar test system to verify their radar sensor reference design based on the industry’s first "28 nm RFCMOS one-chip radar SoC"

The radar target simulator "R&S RTS" for automotive radar and in particular its ability to electronically simulate very close-range objects, has been used to verify the performance of NXP Semiconductors’ next-generation radar sensor reference design. This collaboration enables the automotive industry to take another step forward in the development of automotive radar, the principal technology that enables advanced driver assistance systems (ADAS) and autonomous driving features.

Engineers from both companies conducted a comprehensive series of tests to verify the new sensor reference design which is based on a "28 nm RFCMOS radar one-chip SoC" from NXP. The radar test system combines the "R&S AREG800A" automotive radar echo generator with the "R&S QAT100 antenna mmW" frontend, offering unique short-distance object simulation capabilities as well as superior RF performance and advanced signal processing with many advanced functions. This enables realistic tests of next generation automotive radar applications and brings automotive industry’s vision of fully autonomous driving one step closer.

NXP breaks ground with 28nm radar sensor for advanced automotive safety

NXP’s next generation automotive radar sensor reference design is enabled by the industry’s first "28 nm RFCMOS radar one-chip SoC" family leveraging the "R&S RTS" radar test system. The radar sensor reference design can be used for short, medium and long-range radar applications to serve challenging New Car Assessment Program (NCAP) safety requirements as well as comfort functions like highway pilot or urban pilot for the fast-growing segment of L2+ and L3 vehicles.

The "R&S RTS" is the only test system suitable for complete characterization of radar sensors and radar echo generation with object distances down to the airgap value of the radar under test. It combines the "R&S AREG800A" automotive radar echo generator as a backend and the "R&S QAT100" antenna array or the "R&S AREG8-81S" as a frontend. The technically superior test solution is suitable for the whole automotive radar lifecycle including development lab, hardware-in-the-loop (HIL), vehicle-in-the-loop (VIL), validation and production application requirements. The solution is also fully scalable and can emulate the most complex traffic scenarios for advanced driver assistance systems.

Close cooperation between NXP and Rohde & Schwarz

Adi Baumann, Senior Director ADAS R&D, at NXP Semiconductors says: “We have been collaborating closely and successfully with Rohde & Schwarz for many years on the verification of our automotive radar sensor reference designs. Rohde & Schwarz’ cutting-edge automotive radar test systems allows us high-quality and highly efficient validation of our automotive radar products and proves outstanding performance of our radar one-chip. The level of experience, quality and support that Rohde & Schwarz provides to NXP is making a difference.”

Gerald Tietscher, Vice President Signal Generators, Power Supplies and Meters from Rohde & Schwarz says: “We are grateful for the collaboration with NXP to accelerate the deployment of advanced automotive radar sensors based on 28 nm automotive radar chips. They serve ever more challenging NCAP safety requirements and will help enable new safety applications. Our experience in automotive radar testing allows us to provide a best-in-class test solution for this radar sensor design based on the industry’s first '28 nm RFCMOS one-chip radar SoC'.”
