ABSTRACT:
A local positioning system is proposed for wirelessly locating an object using existing features within a static environment, such as walls, as the references for determining the position of the system. An antenna16attached to the object transmits RF signals which are reflected by the surroundings. During a training mode, the reflected signals are used to train a neural network22, 43to map the position of the object to the characteristics of the reflected signals. During a working mode, the trained neural network is to identify the position of the object based on reflected signals in working mode. Optionally, the reflected signals may be subject to a clustering process before input to the neural network.
