Abstract
This paper presents a novel frequency modulated continuous wave (FMCW) radar response simulation method with a focus on human gesture detection. Through use of 3D motion captured by an infrared (IR) camera system and data processing, a realistic and computationally efficient simulation is produced. The gestures considered are a hand raise (up-down), right-left arm sweep, and push forward. The high efficiency in simulation is due to a simplified yet effective approach to radar cross section (RCS) calculation and radar-detected signal integration. This allows for the simulation to run smoothly while still resulting in realistic approximations of both range profile and doppler response of gestures. The simulated results are validated with experimental results detected by an Infineon 60-GHz radar.
