Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of geological detection equipment, and in particular to a geological radar. BACKGROUND

[0002] The geological radar uses ultrahigh frequency electromagnetic waves to detect the distribution of underground medium. Its basic principle is that the transmitter transmits a pulse electromagnetic wave signal with a center frequency of 12.5M to 1200M and a pulse width of 0.1ns through the transmitting antenna. When this signal encounters a detection target in the rock layer, a reflected signal is generated. The direct signal and the reflected signal are input to the receiver through the receiving antenna, and are displayed by the oscilloscope after amplification. According to whether there is a reflected signal on the oscilloscope, it can be judged whether there is a measured target; according to the arrival lag time of the reflected signal and the average reflection speed of the target object, the distance of the detection target can be roughly calculated.

[0003] The existing geological radar is usually in the form of a trolley and moves on the ground. The geological radar performs geological detection on the ground during movement, and the detection personnel can observe the detection data of the geological radar in real time, which facilitates better geological detection.

[0004] However, due to uneven ground, the geological radar is prone to vibration, shaking, and shaking during movement, which not only affects the observation of the detection data of the geological radar by the detection personnel, but also affects the data obtained by the geological radar during geological detection.
