| 摘 要： | 本文分析了基于四阶累积量的测向方法不能正确测量多径信号方向的原因，提出了一种多径环境下的基于四阶累积量的新型测向方法。该方法利用零点领处理方法抑制多径信号，然后采用四阶累积量进行阵列扩展测向。计算机模拟结果表明该方法在多径环境下具有良好的性能并且可能实现对足够多的信号进行测向。

| Abstract: | The forth-order cumulant-based DoA methods can be used on suppressing gaussian noises and extending array aperture. It fails in DOA estimation of the cohereni signal in multipath environment Based on theforth-cumulant, a novel approach is presented in the paper. By spatial null preprocessing, the approach can estimate DOA of the coherent signal. The method is verified by the simulation experiment. |
