Description: 提出了一种新的宽带DOA估计方法:频域子空间正交性测试方法(TOFS:Test of orthogonality of frequency sub- space)。该方法通过同时测试频域信号共同带宽内各频段噪声子空间与阵列流形之间的正交性来进行DOA估计。与宽带相干信号子空间方法不同,TOFS方法不需要任何初始值的预估及聚焦操作。与宽带非相干信号子空间方法也不同,TOFS方法同时测试各频段噪声子空间与阵列流形之间的正交性。本文仿真了TOFS与IMUSIC、CSSM、TOPS的性能比较。仿真结果表明TOFS方法在中等信噪比以上时有较好的性能,且避免了TOPS方法中常出现的伪峰。 -Proposed a new broadband DOA estimation methods: subspace orthogonal frequency domain test methods (TOFS: Test of orthogonality of frequency sub-space). The method by simultaneously testing the frequency domain signal bandwidth of each band noise common sub-orthogonality between space and the array manifold to be DOA estimates. And broadband coherent signal subspace different methods, TOFS method does not require any initial estimate and focusing operation values. And broadband incoherent signal subspace methods are different, TOFS method for simultaneous testing of each band orthogonal noise subspace and the array manifold between. This paper compares the performance TOFS simulation and IMUSIC, CSSM, TOPS is. Simulation results show that the method TOFS better performance when more moderate SNR and spurious peaks TOPS method avoids the often occur. Platform: |

Description: In this paper, we firstly construct a wide-band undersampling array, then present a novel frequency and
direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz). Choosing a set
of appropriate sampling frequencies and antenna spacing, the method can provide unambiguous frequency
and DOA estimation under the sub-Nyquist spatio-temporal sampling. The proposed method can reduce
the computational complexity as it does not need the 2-D spectral peak search and high-dimensional
eigen decomposition. In addition, the proposed method uses the temporal filtering to cascade the
frequency estimation and DOA estimation so that the DOA estimation results are automatically paired
with corresponding frequency. Simulation results demonstrate the effectiveness of the novel method. Platform: |

Description: 述是经典MUSIC算法的基本原理，许多限制是可以放宽或取消的。首先，关于均匀线阵的限制不是必须的，实际中可采用几乎是任意形状的阵列形式，只要满足在个独立信号源的条件下，矩阵具有个线性无关的列就可以了。其次，天线阵元在观测平面内无方向性这一点也不是必要的，而且还可以考虑三维空间的DOA估计问题，即不仅估计信号的方位角，还要估计它的俯仰角，当然MUSIC算法还用于频率、方位和俯仰的联合估计。-Above is the basic principle of the classical MUSIC algorithm, a number of restrictions can be relaxed or canceled. First, restrictions on ULA is not necessary, the actual form of an array can be almost any shape, as long as the signal source in the independent condition matrix has linearly independent columns on it. Second, the antenna elements in a plane non-directional observation it is not necessary, but could also be considered DOA estimation of three-dimensional space, that is not only estimated azimuth signals, but also to estimate its pitch angle, of course, also MUSIC algorithm joint estimation for the frequency, the azimuth and elevation.
