As ADAS applications advance to higher levels of autonomous driving, there are more stringent requirements for radar sensors in terms of maximum detection range, range resolution and angular resolution. Long-range radar (LRR) needs a longer detection range within a narrow beam, while medium-range radar (MRR) and short-range radar (SRR) require a broader field of view (FoV) and more precise range and angle resolution capabilities. Current MIMO and RF phased-array architectures shown in Fig. 10.1.1 (top) have difficulty achieving optimal performance over the above three modes,
