本文给出了应用于调频连续波(FMCW)探测雷达数字信号处理中的快速傅里叶变换(FFT)方法,并在此基础上给出了针对以建筑物墙中埋藏的金属板和塑料管为探测目标模型的实验结果.该结果表明,快速傅里叶变换(FFT)方法是对探测雷达系统的回波信号进行数字信号处理的有效方法.
This paper presents a fast Fourier transform (FFT) method applied to the digital signal processing of the FMCW detection radar. On the basis of this, aiming at the problem that the metal plate and the plastic pipe buried in the building wall To test the experimental results of the target model, the results show that the fast Fourier transform (FFT) method is an effective method for digital signal processing of the echo signal of the detection radar system.
