- In this paper, a TDOA (Time Difference of Arrival) and DOA (direction of arrival) combined passive location system with two stations is studied. The location of a target can be confirmed from the intersection of the hyperbolic curve defined by the TDOA and the direction ray defined by the DOA. A noniterative approach gives an explicit solution for the proposed system. Based on the model of the location system, the location accuracy is analyzed by calculating the geometric dilution of precision(GDOP), which shows how the factors such as TDOA accuracy and DOA accuracy affect the location accuracy. The results are evaluated by computer simulations.
