| Abstract: | The possible ambiguity and non_solution in 2D 3_Station TDOA location systems are discussed in the paper. The relation between ambiguity and the station placement is presented. The relations between non_solution and the station placement and the intention of measuring noise are given. Finally, several methods to solve ambiguity and non-solution problem are purposed. |
