PROBLEM TO BE SOLVED: To provide a positioning device that can eliminate a false image by pairing through a round robin.SOLUTION: A time difference of arrival (TDOA) correlation calculation is performed between reception signals of respective reception sensor pairs by TDOA correlation calculation parts 2a and 2b, and a correlation peak is detected by peak detection parts 3a and 3b. When a plurality of pieces of TDOA is obtained and the number of pieces of TDOA is different for each reception sensor pair, a TDOA inner product matrix calculation part 4 calculates a TDOA inner product matrix. A signal count estimation part 5 estimates the number of signals received by each reception sensor pair on the basis of a calculation result of the TDOA inner product matrix. On the basis of the number of signals estimated by the signal count estimation part 5, a TDOA pairing part 6 pairs the TDOAs obtained by each reception sensor pair with each other from the same radio wave source. |
