POSITION ESTIMATING METHOD AND SYSTEM ON REDUCING ESTIMATED POSITIONING ERROR FOR BI-STATIC RADAR SYSTEM BASED ON CELLULAR NETWORK

The present invention relates to a method for reducing a location estimation error by selectively signal-processing a cellular network-based multi-static radar system and a system thereof. In a location estimation method of a bi-static radar system, a location estimation method includes: a step for detecting a target for estimating a location; a step for judging a location of a target with time of arrival (TOA) based least square method; a step for reducing an estimation error of a location of a target judged using pseudo mono-static information; a step for finally determining a location of a target by comparing the pseudo mono-static information and information of a bi-static system.
