The invention belongs to the technical field of
ground penetrating radar detection, particularly relates to a multi-channel
chaotic ground penetrating radar device for
urban road disease detection, and solves the technical problems that an existing multi-channel pulse
ground penetrating radar is poor in anti-jamming capability and multiple channels cannot work in parallel. Wherein the
signal generation unit comprises a pulse
signal generation module and a
chaotic pulse
signal generation module; the transmitting and receiving unit comprises N transmitting and receiving subunits; each transmitting and receiving
subunit comprises a
local oscillator signal generator, a three-path power divider, a first / second / third
frequency mixer, a first / second power
amplifier, a first / second transmitting antenna, a receiving antenna, a low-
noise amplifier and a
signal acquisition subunit; the signal matching unit comprises N signal matching subunits, and each signal matching
subunit comprises a pulse
detector and a pulse interval matching module; the
clock control unit is connected to the pulse signal generation module, the
chaotic pulse signal generation module, the signal matching subunit and the transmitting and receiving subunit.
