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。
This paper investigates the output signal of an 8mm passive detector in the detection of concrete pavement in a particular mode of operation. The antenna temperature expression is derived and the output signal is simulated using m atlab. Then, the signal is processed by wavelet transform and the possibility of target recognition by wavelet transform is discussed.
