Abstract
In this paper we propose a system that recognizes the location and direction of a target in an indoor environment using impulse radio ultra wideband (IR-UWB) radar. The position measurement using IR-UWB radar uses at least two radars in the conventional algorithm, but assuming that the object is a point, the volume of the object is not considered at all. So it is impossible to predict where the real center of the body is located, and what kind of behavior it is, by only locating it by the reflection signal to the surface of the object. However, if we use the distance information of each of the four radars, we can measure the accurate position of the target and the direction of the target's body. We can also see what behavior patterns we have, and there is no privacy problem at all. In order to verify the proposed system, we installed a radar in four directions in the room and experimented with humans. We could track the position of the object and measure the direction of the body in real time.
