Automotive Radar Testing – FMCW Measurement Challenges and Solutions

Frequency modulated continuous wave (FMCW) signals are a common form of modulated waveform used in radar applications for object detection.  The most common modern-day application is automotive radar, where FMCW chirps may be transmitted in almost every direction for features like adaptive cruise control, blind spot monitoring, reverse warnings, and collision prevention.

This application note will review FMCW signal basics, discuss measurement challenges/solutions, and show how the Spectrum Master MS2760A Ultraportable Spectrum Analyzer can conduct basic FMCW radar testing.
