说明： 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.
Position_Bartlett.m
Bartlett (delay-and-sum) based position estimation. Fixed grid search.
Position_Bartlett_CF.m
Bartlett (delay-and-sum) based position estimation. Adaptive grid search: Coarse-to-fine grid contraction.
Position_MUSIC.m
MUSIC (eigendecomposition of the covariance matrix) based position estimation. Fixed grid search.
Position_MUSIC_CF.m
MUSIC (eigendecomposition of the covariance matrix) based position estimation.
Adaptive grid s)

Position_MUSIC_CF.m
MUSIC (eigendecomposition of the covariance matrix) based position estimation.
Adaptive grid search: Coarse-to-fine grid contraction.
Position_Magnitude.m
Position estimation based on a least squared differences estimator on the sound pressure level differences
between the microphones. Similar to ANSI S1.18 - 1999, but with the source psoition instead of the
ground impedance being estimated.
Position_Phase.m
like the magitude based localization, but using phase differences between the microphones.
