Abstract. The processing of the hodograph data of a monopulse georadar with wireless synchronization is similar to the method of reflected waves in seismic prospecting but has particular differences. The paper describes for the first time the effect of the appearance of steps in the image of the recorded video signal when the receiving and transmitting units of the georadar are moving apart on the example of studies in the mine workings of a potassium salt deposit. Using a kinematic correction in GPR in consideration with the effect of synchronization via electromagnetic wave is especially important for deep research with a large spacing of antenna units.

Key words: bistatic georadar, wireless synchronization, hodograph, video pulse.
