Automated Measurements of 77 GHz FMCW Radar Signals

Frequency Modulated Continuous Wave (FMCW) radar signals are often used in short range surveillance, altimeters and automotive radars. To ensure proper functionality, signal quality measures such as frequency linearity are of great importance.

This application note focuses on fully automated, fast and accurate measurements, of linear FMCW radar signals. It explains the basic signal processing, the impact on radar key performance indicators in case of linearity deviations and explains test and measurement of linear FMCW signals in detail.

Measurement of an FMCW radar signal in the 77-81 GHz band with 500 MHz of measurement bandwidth is demonstrated.
