Patients with neurological diseases often suffer from motor disorders leading to changes in gait pattern and gait disorders. In order to assess the progression of the disease and the effectiveness of therapies, gait analyses are conducted. However, these are often associated with considerable time efforts for both patients and medical staff and require a high amount of space. In this paper, a system based on radar technology is evaluated for gait analysis as an alternative measurement system to the previously used pressure distribution measuring devices and optical motion capture systems. The gait pattern of a test persons were extracted from data and five gait parameters were derived. During the evaluation, the sensor position and height has been varied, and different methods of analysis have been considered. The validity of the system was investigated by quantitatively comparing the measured biomechanical parameters with those recorded by a pressure distribution measurement system. The results show that it is possible to measure medically relevant gait parameters using radar technology.
