Abstract
This paper presents a study of 3D human body localisation using Ultra Wideband technology. Cube and Y shape base station configurations, time of arrival and first peak detection algorithms are used to estimate the position of the sensors that are placed near the surface of the body. Also spherical coordinate system is used to find the direction of the target. A comparative study is done between the TOA and TDOA method in terms of accuracy obtained in estimation of known coordinates. Results show that accuracy in estimation of location of the sensor depends on position it is placed on the human body as the presence of body would cause interference. The overall average accuracy in 3D localisation is around 2.5 to 4.5 cm for TOA method and 3.5 to 4.5 cm for TDOA method.
