Advances and Challenges in Automotive Radar Module Design – Q&A

Below is the question asked during the live event, along with its respective answer.

Q: For the testing of this type of radar, is CATR needed? Or is DFF ok?
A: CATR is normally used with spherical emitters that are then collimated into a single beam, so it mimics the beamforming action of a phased array. If testing directivity of a phased array, DFF is preferred.
