本文提出了一种利用离散付立叶反变换(IDFT)技术完成天线的时域近场测量的方法。
This paper describes a new method which USES IDFT (Inverse Discrete Fourier Transform) technique to do time domain near field measurement for antenna.
将这种滤波器放置在傅里叶反变换产生相关输出之前的联合功率谱面上，该技术可以应用在具有不同灰度图像的模式识别中。
The filter is put on the power spectrum before applying the inverse Fourier transform to yield the correlation output. This technique can be used in pattern recognition of grey level input image.
