Application of transceivers based on ultrawideband chaotic pulses to a positioning problem

The problem of positioning with ultrawideband chaotic radio pulses is considered. The method for determining the time difference between the signals arrival on the basis of the cross-correlation function of the chaotic radio pulses envelope signal is proposed and studied. It is shown that this approach provides the accurate estimate of the time difference of arrival proportional to the frequency band of the radio pulse envelope signal. The method stability to noise is increasing with the chaotic radio pulse base.
