摘　　要：为提高信号到达角(AOA)的测量精度,采用修正的窗函数加权平均算法和基于机动加速度的非零均值时间相关模型的自适应卡尔曼滤波算法,将信号到达角的变化轨迹看作是一种做加速度机动的运动,实现对连续变化信号到达角的参数估计。计算机仿真验证了算法的有效性和可行性,证明该方法有一定的应用价值。We use modified rectangular function weighted average algorithm and adaptive kalman filter algorithm which is based on non-zero mean time-dependent model of maneuver acceleration in order to improve the measuring accuracy of signal DOA. The changing tract of signal DOA can be seen as a maneuver acceleration movement, and it realizes the parameter estimation of continuously varied signal DOA. Computer simulation proves that the effective and feasible algorithm in this paper has reference value,
