TOA based Target Tracking using Optimal Estimation Methods

Position is one of the essential attributes of an object. With the development of wireless communication and ranging technology, localization algorithms should also been investigated to improve its accuracy. Ultra Wideband (UWB) has the potentials of low cost and high precision. However, its accuracy is susceptible to environment, such as non-line-of-sight conditions. There is a pressing need for a suitable algorithm to reduce the impact of ranging errors, and ensure the performance of the positioning systems when the ranging error varies.
