Description: 传输矩阵法计算啁啾光栅反射谱
本节中给出传输矩阵法计算啁啾光栅反射谱和
时延的完整M at lab 程序实例, 本段代码在
M at lab513 和W indow s2000 环境中运行通过。运行结果如图8 所示。可以改变光栅长度、有效折射率、折射率调制深度、啁啾系数等参数来获得不同参数下光栅反射谱和时延曲线。如果打开“％ 切趾”行的屏蔽符“％ ”则可得到切趾后光栅反射谱和时延特性曲线, 此时计算所得的曲线将比图8 中所示的曲线平滑很多。-Transfer matrix method to calculate reflection spectrum of chirped grating is given in this section transfer matrix method to calculate chirped grating reflection spectrum and the delay of a complete example of M at lab procedures, the above code in M at lab513 and W indow s2000 environment to run through. The results shown in Figure 8. Can change the grating length, the effective refractive index, refractive index modulation depth and chirp coefficient parameters to obtain different parameters of grating reflection spectrum and the time delay curve. If you open Apodization line shielding Fu can be grating after apodization reflection spectrum and the delay characteristic curve, the curve at this time will be calculated as shown in Figure 8 a lot of curve smoothing.

Description: 基于高阶累积量的生命微动信号检测方法的研究成果，发表在IEEE Transaction Geoscience and Remote Sensing 期刊上-The research on vital information extraction meets a
lot challenges due to the narrow bandwidth and low signal-to-noise
ratio of a vital sign in real environment. In this paper, a novel
noncontract vital sign detection method based on multiple higher
order cumulant is presented. According to the characteristic of
vital sign for impulse ultrawideband radar, the quasi-periodic
reflected echo in slow-time is analyzed. The novel method is
theoretically deduced from fourth-order cumulant. It is proved
to be better than the reference fast Fourier transform method
by simulation and experiment. By using the new method, the
range position and frequency information of life can be extracted
accurately and automatically. Platform: |
