Description: 由地面效应反转和一个单一的垂直阵列源距离和高度确定
-------------------------------------------------- ---------------------------------------------
matlab文件的集合来确定与一个单一的垂直阵列的来源范围，并高度。
使用一个分析传播模型来计算上述的阻抗平面的声场。
用途要么转向响应功率（SRP）与Barteltt或MUSIC波束形成器或幅度/相位差异
各麦克风之间。-Source distance and height determination by ground effect inversion and a single vertical array
-----------------------------------------------------------------------------------------------
A collection of Matlab file to determine the source range and height with a single vertical array.
Uses an analytical propagation model to calculate the sound field above an impedance plane.
Uses either steered response power (SRP) with Barteltt or MUSIC beamformer or the magnitude/phase differences
between the microphones.

Description: 仿真实现了MUSIC、Beamformer、Capon功率谱，并未实现线性预测功率谱估计（未找到方法）。由实验结果我们可以得出结论MUSIC的估计效果最好，它可以区分800、850处来波，其他角度也可区分。-Simulation of MUSIC, Beamformer, Capon power spectrum, did not realize the power spectrum estimation linear prediction (not way to find). From the experimental results, we can draw the conclusion MUSIC best estimate of the effect, it can be distinguished to wave at 800, 850, other angles can also be distinguished. Platform: |
