摘　　要：空间谱估计测向具有高精度、高分辨率等优异性能,它基于多信道接收机和阵列信号处理技术,可以分别得到空间中同频多个信号的方位,并且相对干涉仪等其它方法具有较高的测向精度。针对空间谱估计中的经典算法-MUSIC算法,介绍了一种基于二维MUSIC算法的空间谱测向系统,并对整个系统的硬件单元及工作流程进行了描述,最后给出了系统的实测数据。The technology of spatial spectrum estimation has the excellent performance of high precision and high resolution in direction-finding. Based on multi-channel receiver and array signal processing technique, the technology can obtain the different DOAs of multi-signal with the same frequency simultaneously. Aiming at the MUSIC algorithm, the typical algorithm of spatial spectrum estimation, a DF system based on 2D MUSIC algorithm is introduced. The hardware structure and working principle of the system are described, and finally the experimental data is presented.
