“…In general, the smallest Path-dif that the system can detect is equal to c/2Δ f . In our case, for a frequency bandwidth of 2 GHz, the Path-dif is To improve the accuracy of the azimuth angle measurement without increasing the frequency bandwidth, many solutions are proposed, such as [11] which exploits the phase difference of a CW signal. With a d baseline = 29 cm and a CW signal at 2.45 GHz, the azimuth angle uncertainty range is equal to +/-2°.…”

This paper shows that the accuracy of azimuth angle measurement for an interferometric localization system used to locate tags in its Line-of-Sight (LoS) can be improved by exploiting Impulse Radio-Ultra WideBand (IR-UWB) signals and without increasing the frequency bandwidth. This solution uses a Phase Correlation (PC) method, initially applied for Continuous Wave (CW) signals, adapted for Ultra WideBand (UWB) pulse signals. The obtained results are compared to those computed by a classical Energy Detection (ED) method where it becomes impossible to estimate azimuth angles for tag positions close to the orthogonal centered axis of the localization system baseline.

“…Usually performed in indoor environments, location matched to such applications suffers deeply from multipath contributions. Actually mainly based on the time of arrival [2] or the phase difference [3] the location is dramatically degraded by multipath even if they are not strong, and hence put a serious strain on the location budget error. To combat these muitipath, GPS promoters use numerous pseudo lites [4] not easy to handle and not really suited for ad hoc networks.…”
