—This paper designed an improved positioning system which employed a proposed improved Sinc interpolation algorithm to reduce the sampling frequency of the system , calculated time difference of arrival (TODA) values with matched filter, estimated the position of the target node by Chan's algorithm and used Chauvenet criterion to optimize the positioning results. Analysis and simulation results showed that the algorithm could reduce the sampling frequency to a great extent while ensuring the accuracy of the positioning system.
