Robustness is provided to the system by means of a Slow Frequency-Hop Spread Spectrum modulation and a robust 2D AoA estimation method with a Uniform Circular Array (UCA). In simulation, the system shows an accuracy of 1.7 degrees in the orientation estimates and location estimates under 1cm in 95% of cases under conditions of noise and reverberation.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2008 IEEE||Keywords:||ToA; AoA; Orientation; Location; Ultrasound||DOI:||10.1109/ISSSTA.2008.156||Language:||en||Status of Item:||Peer reviewed||Conference Details:||International Symposium on Spread Spectrum Techniques and Applications (ISSSTA), Bologna, Italy, 25 - 28 August, 2008|
