In recent years, the population of elderly people is increasing rapidly. The shortage of workers who take care of them is becoming serious. Based on these situations, the burden of the care workers has become a big social problem. Therefore reducing the care workers burden is important. In this paper, we propose the novel behavior detection system using several ultrasonic radars. In the system, a new decoupling method, in which the transmitting time periods of ultrasonic wave is altered, is introduced into the ultrasonic radars. The effectiveness of the method was confirmed by the field tests with a healthy male in 20 experiments. However, further field tests with elderly persons in actual living facilities are necessary to verify the usefulness of the system for them. This system can be useful for safety management for the elderly people, and reduce the work of a care worker.
