Abstract

The invention provides a geological exploration radar. The geological exploration radar comprises a frequency reconfigurable antenna module used for receiving or sending signals of all frequency bands; and the frequency reconfigurable antenna module is made of a graphene material. By means of the reconfigurable antenna, the geological exploration radar can dynamically select different working modes according to the difference of environments, so that one antenna achieves the function of a plurality of antennas. With the geological exploration radar of the invention adopted, the problems of electromagnetic interference and system miniaturization can be effectively solved; and the frequency reconfigurable antenna based on the graphene material is adopted. The working frequency of the antenna has a continuous adjustable characteristic within a specific frequency band range, and other radiation characteristics such as far-field radiation patterns and polarization modes of the antenna are kept unchanged.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a geological detection radar. Background technique [0002] Geological detection radar is a kind of geophysical detection instrument. The geological detection radar uses the transmitting antenna to transmit high-frequency broadband electromagnetic waves, and the receiving antenna receives the reflected waves from the medium interface. When the electromagnetic wave propagates in the medium, it will be reflected when it encounters an interface with electrical differences, and the spatial position, structure, shape and burial depth of the medium can be inferred according to the characteristics of the received electromagnetic wave, such as waveform, amplitude intensity and time change. At present, it is widely used in many engineering fields such as geological survey, non-destructive quality inspection of construction projects, and underground pipeline inspection. [0003...
