Abstract: PURPOSE: Powerless wireless signal analysis system and a method thereof are provided to increase utilization of a sensor by obtaining more accurate information by accurately analyzing a signal of a sensor. CONSTITUTION: A signal generator(100) transmits a vector signal for signal analysis. Also, the signal generator transmits the vector signal for signal analysis to a powerless wireless sensor(200) through the first antenna using a divider(110) having a first antenna and a second antenna, and transmits a signal analysis apparatus(300) through the second antenna. The powerless wireless sensor transmits a return signal corresponding to the vector signal by receiving a vector signal generated in the signal generator and includes a circulator(220) having the first antenna and the second antenna. A first port of the circulator is connected to the first antenna receiving a vector signal and a second port of the circulator is connected to the signal generator generating a return signal corresponding to the vector signal and a third port of the circulator is connected to the second antenna generating a return signal.

Abstract: A method for estimating a position of an object using a collision signal of a RFID reader comprises the steps of: transmitting a signal to generate the collision signal of the reader by a plurality of the RFID readers if the RFID readers recognize a target tag in the initial overlapped region; minimizing the expected range while reducing the power of the RFID readers based on whether the target tag is detected from the RFID readers; selecting a reference tag by increasing the power of the RFID readers with the reduced power and extending the detection area; and estimating the position of the target tag based on the reference tag. [Reference numerals] (A1) Estimated region is the region excluding a detection region of one RFID reader after the power is reduced in a detection region of one RFID reader; (A2) Estimated region is the remaining region excluding the detection region of the RFID reader after the first power is reduced; (A3) Estimated region is an overlapping crashed region in an initial detection region capable of recognizing a tag by a plurality of RFID; (AA) Start; (BB) Plurality of RFID readers transmits signal to generate the reader signal collision when a plurality of RFID readers recognizes a target tag in an initial overlapping region; (CC) Plurality of RFID readers recognizes the target tag in the collision overlapping region; (DD) Reduce the power of the RFID reade for recognizing the power of RFID readers until the target tag is not recognized; (EE) Firstly reduce the power of the RFID readers until one or more RFID readers is not recognized; (FF) Recognize the target tag from one RFID; (GG) Secondly reduce the power of the RFID power recognizing the target tag until the target tag is not recognized
