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

摘要

Disclosed are a multistatic PCL target position estimation system and method using an FM broadcast network. A receiver selection module for selecting an optimal receiver for estimating the position of a target among a plurality of receivers distributed on the ground connected to the FM broadcasting network; A target position estimation module for estimating a position of a target using time difference of arrival (TDOA) information of an FM signal received at each receiver selected by the receiver selection module; The filtering module is configured to filter and output a target position estimated by the target position estimation module. According to the above-described multi-static PCL target position estimation system and method using the FM broadcasting network, it is configured to accurately calculate real-time three-dimensional position information of a target in a complex commercial broadcasting network environment, thereby using a conventional infrastructure broadcasting network in a wide range of areas. There is an effect that can obtain accurate target information. In particular, there is an advantage that it is easy to implement the cost reduction. In particular, since the optimum receiver for calculating the target position information is calculated in real time among the various receivers of the broadcasting network and the 3D position information is calculated using the same, the accuracy and efficiency of the target information calculation can be improved.
