Optimal Location Method of Spontaneous Data Fusion based on TDOA / AOA

Aiming at the problem of positioning underwater targets in a wide range of sea areas, the modern optimization technology simulated annealing algorithm is introduced into the non-linear programming of the multistatic sonar azimuth estimation. According to the development trend of long-distance wireless positioning technology
^[1]
, the data fusion positioning model based on Time Difference Of Arrival(TDOA) and Angle of Arrival(AOA) is analyzed, and a TDOA/AOA data fusion positioning method based on the simulated annealing(SA) algorithm is proposed. Simulation experiments are conducted to analyze the positioning accuracy of this method in a wide range of sea areas under different working conditions, which verifies the effectiveness and feasibility of the method.
