Automotive Radar – Chirp Analysis with R&S RTP Oscilloscope
FMCW radar sensors are used in vehicles for adaptive cruise control and for blind-spot, lane-change and cross-traffic assistants. Radar sensors for acquisition of the surroundings are key components for future vehicles with semi-autonomous and fully autonomous driving. Autonomous driving requires radars that reliably detect objects in the surrounding area. Radar makes it possible to quickly and precisely measure the radial velocity, range and azimuth, and elevation angle of multiple objects. For this reason, the automobile industry is increasingly using this technology in advanced driver assistance systems (ADAS).
Rohde & Schwarz offers T&M solutions for generating, measuring, and analyzing radar signals and components to ensure trouble free operation of these sensors. The high-performance oscilloscope R&S® RTP with four measurement channels is the perfect solution for multi-channel measurements on MIMO radar sensors and correlation with other signals e.g., power rails, whereas a spectrum analyzer such as the R&S® FSW85 offers highest dynamic up to 85 GHz.
This application note focuses on how to measure and analyze FMCW radar signals with up to 6 GHz bandwidth with an R&S® RTP oscilloscope. On-board analysis features for pulse and chirp analysis for single- and multi-channel measurements will be addressed as well as the combination of oscilloscope and R&S® VSE software. Measurement of an FMCW radar signal in the 77 - 81GHz band with 4 GHz bandwidth is demonstrated.
