3D Comform Radar System for Detection of Motion and Falls in Spatial Application

Enabling a long, self-determined life in old age contributes to increasing the quality of life of senior citizens. The prerequisite for this is the timely recognition of dangerous situations and the subsequent initiation of assistance measures. For reasons of personnel and finances, detection must be solved with the aid of technology. For reasons of acceptance, this technology should neither interfere with people's privacy nor be clearly visible in the room. A radar system for recording and evaluating movement profiles in a room was developed to detect hazardous situations. The analysis of the motion profiles is used to derive hazardous situations. The radar system, which consists of four radar modules, has a detection range of 360° with an angular resolution of 12°. This makes it possible to distinguish between people or objects in addition to detecting movements. Through the joint development of hardware and software, the system could be miniaturized and integrated into an overhead luminaire. It remains invisible to the user.
