Major parts investigation report of Elut’s 79GHz millimeter wave radar


	AG409-RS01	Appearance of PCB

Overview

　Sensors used for autonomous driving include imaging sensors and LiDAR, but millimeter-wave radars are increasingly used because they are less susceptible to weather and environmental conditions.

　The mainstream is 76.5GHz millimeter-wave radar, which can detect objects as 1m as possible at a distance about the front 200m of vehicles for long distances. (Theoretical range resolution is 15cm.) The theoretical range resolution of 79GHz millimeter-wave radar is greatly improved in 3.75cm. For this reason, medium-range radars are becoming the mainstream of short-range and medium-range radars, because medium-range radars can detect objects as 10cm as they are at a distance of 100m, and short-range radars can detect objects as cm as they are at a distance of 10m. This device is used as a surveillance radar in the rear of vehicles because it is used for short distances and has 1m detecting distances.

　In this analysis, we disassembled 79GHz millimeter-wave radar AG409-RS01 manufactured by Elut and investigated the main parts.
