“…The used values of the measuring resistor are RM=100 Ω for comparison with the results obtained in [4] and RM=1 Ω to maximize the current response i1(t) from marker. The time course of the current i1(t) for model of marker localization with two resistors is shown in Fig.…”

“…Note that the current maximum was calculated in the time interval after the transients of the excitation current decay. For comparison of the presented analysis results and the results from simplified model calculated in [4] the case when RD=RM was calculated, too. This case is identical with the simplified model and the comparison is shown in Fig.…”

“…An important quantity in the models presented in next chapters is the mutual inductance M between marker and locator coils which depends on the geometrical arrangement of coils according to equation [1], [4], [8]: where rR is radius of RFID locator antenna coil, rT is radius of marker coil, x is distance between the locator antenna and the marker and θ is the angle between coil of locator antenna and marker coil (note that if θ=0 ° then coils are parallel).…”

“…Moreover, the depth of marker can be estimated by RSSI (Received Signal Strength Indication) similarly as described in [2], [3]. In [4] the authors describe marker localization methods based on marker damped oscillations and on continuous generating of electromagnetic waves. This work extends the analyses of RSSI based marker localization methods.…”

-The presented paper is focused on analysis of two methods of marker localization. The markers are passive RFID transponders (without or with identification chip) consisting of tuned LC circuit and being used to mark and trace underground networks such as cables and pipes. Localization of the marker is based on evaluation of signal amplitude received from the excited marker, i. e. it is RSSI based localization method. The excitation of marker can be periodically repeated or continuous. In the first case the localization process consists of two stages -excitation and receiving of marker damped oscillations, in the second case the amplitude of continuously generated excitation signal is decreased by vicinity of the marker. Both localization methods are mathematically analyzed by modeling of their circuits using differential equations. The results of analysis are used to compare both methods and to evaluate their suitability for practical utilization.
