DEVICE FOR INTERFERENCE OF A WAVEGUIDE TRANSMISSION LINE IN THE SYSTEM FOR MEASURING THE SPATIAL POSITION OF THE PUNCHING HEAD OF THE UNDERGROUND LAYING OF THE COMMUNICATION TRAFFIC

Abstract

The article discusses a way to improve the efficiency of the measuring system for determining the spatial position of the piercing head of the soil puncture mechanism, in which at a frequency of 5 GHz, hollow metal rods can be used as a transmission line of the measuring signal. Considering that such a line, due to its inhomogeneity, changes the polarization of the transmitted wave, a design is proposed for a device for interfacing a circular waveguide with a coaxial input of a receiving device, which allows increasing the signal level at its input. The conducted experimental studies on the model of a transmission line with an operating frequency of 10 GHz confirmed the effectiveness of the proposed interface device.
