Metal detector for buried abandoned japanese chemical weapons |
| abstract |
Disclosed is a metal detector for buried abandoned Japanese chemical weapons, comprising: a frequency selecting unit used to adjust a frequency of a sounding signal; a transmitting circuit electrically connected to the frequency selecting unit and used to transmit the sounding signal; a receiving circuit used to receive a signal reflected by a detection object illuminated by the sounding signal; an analog-to-digital conversion unit electrically connected to the receiving circuit and used to transform the reflected signal from an analog signal to a digital signal; and a control unit electrically connected to the analog-to-digital conversion unit. The frequency selecting unit can switch between different frequencies for outputted signals to detect different iron compounds, thereby improving detection precision. |
