摘要
研究用二维MUSIC算法,解决阵列处理二维多源测向的快速实现问题。利用阵列流形具有的对称性,减少阵列流形和空间谱的计算量。在判定出信号源个数后,有选择地使用信号子空间或噪声子空间去计算空间谱,进一步减少计算量。采用2片ADI公司的高性能DSP芯片(ADSP21160),用并行处理方法实现了二维多源测向的实时处理。
The fast implementation of 2-D multiple sources DOA estimation by MUSIC algorithm is dealt with. Using the symmetry of array geometry, the computational load of array geometry and spatial spectrum can be reduced. After acquired the number of signal sources, by choosing the signal subspace or noise subspace the spatial spectrum is computed. So the computational load can be reduced further. The idea has been implemented on two ADSP21160 DSP chips in parallel version, and the real-time requirement has been met.
