140GHz Automotive Radar — Sense and Nonsense

A new band for automotive radar exploiting higher frequencies is a natural evolution to further enhance radar performance. Increased resolution on all dimensions is the promise, the penalty to pay is maximum range. So what will be the role of 140GHz in next-generation automotive radar perception? This critically depends on technological progress, but even more so on the economics and on progress within the broader sensor fusion context. In this workshop presentation, we will give an overview on what we have learned from our 140GHz work so far on circuits, antennas and packaging and we will speculate on future developments in this field.
