摘要
本文研究在一种特定工作模式下,8mm无源探测器探测水泥路面时的输出信号。推导出了天线温度表达式并用m atlab对输出信号进行仿真。然后用小波变换对仿真信号进行信号处理,并讨论了利用小波变换进行目标识别的可能性。
The output signal that is generated when an 8mm passive probe detects the cement road in a special working mode has been studied in this paper. The expression of the antenna temperature is derived and matlab is used in the emulation of the output signal. Then wavelet transform is used in signal process and the possibility of its usage in target identification is discussed.
