Method and system for assisting in the characterization of the environment by the radiofrequency signals ultra wide band.

摘要

The present invention relates to the characterization of the environment from radio signals ultra wideband (uwb). It emits pulses, and it compares the form of wave received by the wave forms of interaction predicted corresponding to well defined between the wave and its environment. The comparison is done by searching for the correlation maximum time. The interactions can be in particular of the reflections of the wave on the walls or obstacles. The deformations are highly dependent on the nature of the materials and of the directions in which are emitted and received the pulses. If it is stored waveforms predicted for various pairs of the direction of emission (ea) and reception (ar), it is possible for these operations of correlation find which is located a wall which has given rise to a reflection.
