时延估计及TDOA定位

该资源包含多种时延估计的方法，涉及时域、频域、自适应方法等，并利用多个分布的传感器数据，采用TDOA的方法估计出关注目标的位置。资源内包含matlab源代码、GUI代码、传感器数据等。

%CLEAN_SIGNAL Cleans the signal （preconditioning）
%   It applies the selected preconditioning methods in folder ‘preconditioning‘
%   so detection will be then easier.Filters must be passed as strings inside
%   ‘preprocessing_methods‘ cell array. Available options are:
%   {remove_mean banda_pass time_gain spectral_substraction
%   percentiletk}

    addpath（‘preconditioning‘）

    % TK should‘nt be applied as it is only convenient for impulsive signals and
    % minke whales are not so TK removes them. Not useful in our case.
