Abstract :
In this paper we present a numerical evaluation of a RF localization system to determine the position of a functional radio capsule released in the ventricular system of the brain. The concept is based on an AoA estimation using short UWB pulses. Although first results are quite stimulating, the initial localization accuracy is too poor for practical applications. It has been shown that this is mainly cause by NLoS waves reaching certain reference stations faster than waves travelling along the desired LoS path due to significant higher phase velocities in the cranial bone or the sinus cavities compared to the different types of brain matter.
