| Summary: | An experimental analysis of the factors which affect the sensitivity of the Ported Coaxial Cable Sensor (PCCS) system is presented. The measured response profile of the test system is compared against variations of cable separation distance, soil conductivity and permittivity, and magnetic field intensity above the transmitter cable. These experiments show that higher conductivity and permittivity of the burial medium results in a decrease in the strength of the magnetic field above the transmitter cable, and that this results in a decrease in response number. The results of these experiments are compared with the results obtained from a theoretical analysis of a simplified model. An experimentally derived relationship between cable separation distance and response number, which is valid for all soil types, can be applied to predictably minimize variations in sensitivity, resulting in a response ratio for each cell which will not exceed 3:1. |
