MULTISTATIC PASSIVE COHERENT LOCATION SYSTEM AND METHOD FOR ESTIMATING TARGET LOCATION USING FM NETWORK

摘要

Disclosed are a multi-static PCL target location estimation system and method using an FM broadcasting network. The multi-static PCL target location estimation system comprises: a receiver selection module for selecting an optimal receiver for estimating a location of a target among a plurality of receivers distributed on a ground connected to an FM broadcasting network; a target location estimation module for estimating a location of a target by using time difference of arrival (TDOA) information of an FM signal received from each of the receivers selected by the receiver selection module; and a filtering module for filtering and outputting a location of a target estimated by the target location estimation module. According to the system and the method of the present invention, 3-dimensional position information of a target is accurately calculated in real time in a complex commercial broadcasting network environment, and thus it is possible to obtain accurate target information in a wide area by using an existing infra broadcasting network. In particular, costs may be reduced, and implementation may be facilitated. In particular, the present invention is configured to calculate an optimal receiver for calculating target location information among various receivers of a broadcasting network in real time and to calculate 3-dimensional location information by using the same, thereby improving accuracy and efficiency of target information calculation.
