Two-dimensional Location Algorithm Based on Time Difference of Arrival
Abstract
Service robots, driverless cars and unmanned aerial vehicles gradually appear in people's life with the development of new technologies such as internet of things, big data, cloud computing and artificial intelligence. These applications rely on location technology. In order to meet the location requirements, it is necessary to realize two-dimensional location, to improve the locating accuracy and to reduce the locating error through relevant processing. In this paper, we study two-dimensional location algorithm based on time difference of arrival. At first, the mathematical basis and principle of the location algorithm are analyzed. Then, the location algorithm is simulated based on MATLAB to verify the algorithm. At last, the location algorithm is deeply studied and the optimization scheme is proposed. The research has important reference value for the practical application of location algorithm based on TDOA.
