Zusammenfassung: | The invention discloses a shallow geologic body high-frequency pseudo-random spread spectrum coded signal detection device and a use method. The detection device comprises a signal transmitter and a synchronous signal receiver, the signal transmitter comprises a single-chip microcomputer, a programmable logic gate array, a power amplifier module, a DC power supply, a display module, a GPS synchronization module, a communication module and a storage module. The synchronous signal receiver comprises a pre-amplification circuit, a band-pass filter circuit, a program control amplification circuit, an analog-to-digital conversion circuit, a programmable logic gate array, a single-chip microcomputer, a communication module, a display module, a GPS synchronization module and a storage module. A high-frequency pseudo-random spread spectrum coding sequence signal which is output to the ground by a shallow geologic body of 2m-100m, has a certain voltage and has a frequency band range of 1KHz-300KHz is output to the gro |
