Automotive radar test system enhances road safety

The E8740A Automotive Radar Signal Analysis and Generation Solution from Keysight Technologies enables radar-based, advanced driver assistance systems to proactively detect and mitigate risks of collisions. Automotive radar applications are now an indispensable part of advanced driver assistance systems (ADAS) for both manned and autonomous vehicles.

Growing demand, especially in higher frequencies, such as 79GHz applications, has led to new design challenges for engineers.

“Radar technology in higher-frequencies is critical to significantly improving detection and ranging to different levels, as they take over mission-critical decisions in future autonomous driving scenarios,” said Siegfried Gross, vice president and general manager of Keysight’s Automotive and Energy Solutions business unit. “Ensuring the accurate and robust operation of a radar system in an automotive application relies on the quality and integrity of the radar design. Keysight is committed to helping developers overcome these new radar design and performance verification challenges with our flexible E8740A solution platform.”

The solution leverages Keysight’s leadership in mmWave technology providing signal analysis from 3Hz to 110GHz in a continuous sweep and performs analysis and generation of automotive radar signals across full frequency ranges for 24GHz, 77GHz and 79GHz radar, and provides scalable analysis bandwidth from 2.5GHz to > 5GHz, depending on test requirements.

It offers a scalable test platform that covers present and future frequencies and bandwidths with intuitive tools enabling engineers to rapidly identify, isolate or correct crucial design errors with confidence and it delivers precise measurements that offer greater sensitivity and dynamic range to ensure better SNR, with displayed average noise levels (DANL) of –150dBm up to 110GHz.

The solution uses Keysight’s premiere SystemVue Automotive Radar Library (W1908) to easily generate frequency-modulated continuous waveforms (FMCW) and scenarios.
