Radar-based surveillance of persons from an elevated, tilted position using a two channel 24 GHz FMCW radar system

This paper takes focus on the detection of a single person from an elevated monitoring position using a compact two-channel 24 GHz FMCW radar system. The mounting position and adjustment of the radar system resembles a typical motion detector application, whereas the presented system delivers (x,y) coordinates of the target. The results presented demonstrate a precision in target localisation better than 30 cm for 1 GHz bandwidth at a distance of ≈ 17 m.
