摘要：
In order to solve the problem of multiple sources angle-only tracking, a novel algorithm was proposed by combining the rooting orthogonal propagator method (OPM) and the zero-tracking. As a result, the iterative angle estimation and automatic association were carried out. Two parameters, the forgetting factor and the order of polynomial equation, are involved in the proposed algorithm, and they can be tuned respectively to change the performance of the algorithm, so it is adaptive to the condition that the signal-noise ratio (SNR) and the angular velocity of the sources are changing. The simulation results show that the proposed algorithm possesses a better performance and flexibility than the conventional ones do, and its root mean square error (RMSE) is lower than 0.15° when the SNR is above 0 dB.
