| 摘 要： | 根据噪声调频信号循环平稳特性分析,提出了基于阵列接收信号循环均值-空域处理的波达方向(DOA)估计算法。仿真结果表明:该算法的角度估计性能明显高于比幅比相单脉冲测角法,且在高信噪比环境中,该法的估计性能更好、运算量较小。

| Abstract: | According to the analysis of the cyclostationary properties of noise frequency modulation signals in theory, a direction of angle （DOA） estimation algorithm was put forward based on the cyclostationary mean-space processing method in this paper. The simulation results showed that the performances of the novel algorithm were obviously better than mono-pulse method which was used in angle measurement, and the computation load was lower with better performance under high signal noise ratio. |
