3.2.1.5 Summary

Each sensing architecture has unique strengths and weaknesses. The choice of configuration depends on the specific application requirements, balancing factors like cost, complexity, field of view coverage, and fault tolerance. Understanding these trade-offs is essential for designing robust and effective radar-based safety systems.

In the next chapters we will focus on the mono-static architecture (Single sensor product, Single IWR6843) as it documents the most complete sets of measures at the radar level.
