A medium exploration radar device, wherein the radar probe includes a transmitter that transmits radar waves underground, a receiver that receives radar waves reflected from the underground, and a received signal in the receiver. and a signal processing unit that processes the signals received by the receiving unit using a different dielectric constant for each predetermined number of rotations of the rotating body, and The rotary underground type is characterized in that the burial depth of an underground object is calculated by using the relative permittivity of the underground relative permittivity for the signal with the highest maximum signal level among the synthetic aperture processing signals based on the ratio. Exploration radar equipment.
