The invention discloses an unmanned aerial vehicle aerial ground penetrating radar based on a low-frequency ultra-wideband air coupling antenna. The unmanned aerial vehicle aerial ground penetrating radar comprises an unmanned aerial vehicle, a ground penetrating radar transceiver main body, the low-frequency ultra-wideband air coupling transceiver antenna, a laser radar altimeter, an attitude meter and a GPS module, the ground penetrating radar transceiver main body comprises a signal source module, a transmitter module, a radio frequency cancellation module, a receiver module and a data preprocessing and control module. The low-frequency ultra-wideband air coupling transceiving antenna is adopted, the air coupling problem of the aerial ground penetrating radar is solved, the advantages of a stepping frequency continuous wave radar detection system are utilized, a low-frequency wideband frequency hopping filter is introduced into a receiver module, the sensitivity of a receiver is effectively improved, and the reliability of the receiver is improved. Meanwhile, the maximum radiation direction avoiding technology is adopted in the mounting mode of the receiving and transmitting antenna, and a broadband strong interference signal generated by direct coupling of the receiving and transmitting antenna is eliminated in combination with a radio frequency cancellation module of the ground penetrating radar transceiver, so that detection of a large-depth underground structure is realized.
