R&S supports automotive radar manufacturer Cubtek and NXP to jointly launch 4D imaging radar platform
During the development process of 4D imaging radar, Cubtek used a network analyzer from Rohde & Schwarz (hereinafter referred to as "R&S") to conduct its E-band radio frequency measurements. R&S oscilloscopes and their independently developed application-specific integrated circuits (ASICs) provide ideal measurement tools for the development of automotive radar. Cubtek used the R&S ZVA40 network analyzer and R&S ZVA-Z90 millimeter wave frequency converter in this project.
Future self-driving cars will face complex road scenarios, and 4D imaging radar in the 77GHz band is indispensable. Compared with LiDAR, 4D imaging radar is not easily affected by bad weather and is more in line with the safety requirements of autonomous vehicles.
4D imaging radar covers distance, speed, horizontal angle and vertical angle. Most traditional radar systems currently either lack vertical angle detection capabilities or have very limited vertical angle detection capabilities. Compared with traditional radar systems, 4D imaging radar has made breakthrough progress in horizontal and vertical angular resolution, with an angular resolution close to 1 degree and an angular accuracy of 0.1 degrees.
4D imaging radar has far more antenna channels than traditional radar, and its performance is greatly improved. Traditional radar systems usually have a 3 transmitter/4 receiver antenna structure, while the number of 4D imaging radar transceivers increases exponentially. Since the 4D imaging radar system requires more 77GHz millimeter wave antennas and transceiver chip integration, its millimeter wave antenna, IC adapter design and millimeter wave test verification will play an extremely critical role.
Cubtek Inc., a 77GHz automotive millimeter wave radar manufacturer, cooperated with NXP Semiconductor, a world-renowned automotive radar chip manufacturer, to launch a 4D imaging radar platform at the International Consumer Electronics Show in January last year. NXP imaging radar chipset solution uses the flagship product S32R45 radar MPU and the second-generation high-performance RFCMOS radar transceiver TEF82XX to achieve 12 transmitting and 16 receiving 77GHz antenna channels, and can be expanded to 192 virtual antennas using MIMO technology array. The 4D imaging radar angular resolution has been optimized to less than 1 degree.
When developing 4D imaging radar, Cubtek chose the R&S ZVA40 network analyzer and R&S ZVA-Z90 millimeter wave converter for E-band RF measurements. These instruments provide high performance and high accuracy measurement results in sensitive high frequency environments.
R&S Oscilloscope
R&S digital oscilloscopes include the portable R&S RTH series, R&S MXO4 and the high-end R&S RTO6 or R&S RTP series. The latter can analyze the bandwidth of FMCW signals. The company's self-developed ASIC has the characteristics of low noise and high performance, creating an ideal measurement tool for automotive radar research and development.
