N4ITK Bias Correction. this code is usefull for MRI bias Field removing.

选择五个不同频段的信号对其进行频谱分析，根据信号的频谱特征设计五个不同的数字滤波器，将五路信号合成一路信号，分析合成信号的时域和频域特点，然后将合成信号分别通过设计好的五个数字滤波器，分离出原来的五路信号，分析得到的五路信号的时域波形和频谱，与原始信号进行比较，说明频分复用的特点。(To select one of five different band signal spectrum analysis and design of five different digital filter based on the spectral characteristics of the signal, the the Rd signal synthesizing all the way to the signal analysis in time domain and frequency domain characteristics of the synthesized signal, and then the synthesis signal by five digital filter designed, separated original signal Rd, the time-domain waveform and spectrum analysis the Rd signal is obtained, to be compared with the original signal, the frequency division multiplexed with the characteristics.)

等间距线性阵列，阵元间距d= λ /2，等幅加权，目标方位φr = 0°，无噪声。 分别仿真计算阵元数M=8 、16时的阵列方向图，定性分析产生的原因。（可通过3dB波束宽度计算公式说明） (Equally spaced linear array, the array element spacing d = λ/2, equal amplitude weighted target azimuth φr = 0, no noise. , Respectively, the number of array elements M = 8 and 16 when the array pattern, qualitative analysis to produce simulation. (Available by 3dB beamwidth formula noted))
