摘　　要：为解决对多辐射源同时进行角度跟踪的问题,提出了一种将求根的正交传播算子方法(OPM)与零点跟踪相结合的新算法,实现了迭代的角度估计和自动关联.新算法引入了2个可变参数——遗忘因子和多项式方程阶数,通过调节这2个参数改变算法的性能,从而适应信噪比和目标角速度变化的信号环境.仿真结果表明,与传统方法相比,提出的算法具有更好的跟踪性能和灵活性,当信噪比高于0 dB时,其跟踪均方根误差小于0.15°.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.
