Abstract: The present invention relates to a correction method for transient electromagnetic method-based prediction of water-bearing structure ahead of tunnel wall, which pertains to the technical field of transient electromagnetic sounding method. The correction method includes a method for eliminating effects of transition process in a reception probe and a method of using earth conductivity to eliminate effects of transition process. By using the correction technique, more accurate information about the location, size and shape of the object in front of the tunnel wall can be obtained, which is of great significance to the study of the fine water-bearing geological structure.

Abstract: A buoy-type high-frequency ground wave radar system. A buoy platform is used as an offshore carrier of a ground wave radar. A sky wave emission subsystem is disposed on a shore base and emits a high-frequency electromagnet wave. After the high-frequency electromagnet wave is refracted by the ionosphere and is reflected by the sea surface, a sky wave signal is formed. An attitude measurement subsystem measures and acquires attitude data of the buoy platform in real time. A ground wave radar subsystem receives a ground wave signal by using the ground wave radar, and processes the signal to form a ground wave doppler spectrum. Simultaneously, the sky wave signal is received, ionosphere disturbance compensation is performed on the sky wave signal in a frequency domain and then the sky wave signal is processed to form a sky wave doppler spectrum.
