| titleOfInvention | Position Estimation Algorithm and Position Estimation System for Generating Pulsed High Frequency Signal Using 4 RF Sensors |
| abstract | The present invention relates to an algorithm for estimating a position where a pulse-shaped high frequency signal is generated using four RF sensors and an operation for a position estimating apparatus using an estimation algorithm. Using the installation position of the RF sensor to estimate the position of the signal, the hardware configuration for measuring the arrival time of the pulse signal input to each RF sensor, the arrival time of the pulse signal input to each RF sensor or the arrival time difference between each sensor A position estimation system and a position estimation system of an RF signal source using the algorithm. Since a system for estimating the position of an RF signal source using a conventional antenna or an array antenna is difficult to use for estimating the position of an RF signal generated at a short distance from a RF antenna sensor, the RF signal source is an RF antenna. It should be relatively far from the sensor (Far-Field), and can be applied only when the signal strength is relatively large, and the signal strength change or the phase signal change due to the multi-path dp of the RF signal by the surrounding environment In order to compensate for this problem, complex algorithms must be performed to compensate for this problem, and high-performance / high-performance equipment is needed to perform the direction / position estimation algorithm. 2, 3, 4 and amplifiers 1, 2, 3, 4, 5 for amplifying a signal input from a high frequency signal source; RF to Digital signal converters 1, 2, 3, 4, and 5 for converting RF signals amplified and output from the amplifiers 1, 2, 3, 4, and 5 into digital signals; Estimating the position of the high frequency signal source by measuring the time difference between the high frequency signal source and the RF antenna sensors 1, 2, 3, 4 using the signals output from the RF to digital signal converters 1, 2, 3, 4, 5 A pulse type high frequency signal generation position estimation system using four RF sensors, comprising a time difference counter (TDC), is proposed. Therefore, since the RF signal source position estimation system using the time difference measured by the RF antenna sensor and the antenna sensor can minimize the signal interference generated by the multipath, the position of the RF signal generated at a short distance can be measured. Therefore, it can be effectively used for failure and bad position measurement of electronic products, power systems (eg, electric power equipment, transformer, gas insulated switchgear (GIS), etc.). |
