Abstract:

For the joint time difference of arrival (TDOA) and angle of arrival (AOA) location scene, two methods are proposed based on the rectangular coordinates and the polar coordinates, respectively. The problem is solved perfectly by calculating the target position with the joint TDOA and AOA location. On the condition of rectangular coordinates, first of all, it figures out the radial range between target and reference stations, then calculates the location of the target. In the case of polar coordinates, first of all, it figures out the azimuth between target and reference stations, then figures out the radial range between target and reference stations, finally obtains the location of the target. Simultaneously, simulation analyses show that the theoretical analysis is correct, and the proposed methods also provide the application of the joint TDOA and AOA location algorithm with the theoretical basis.
