Aiming at the shortcoming of the traditional weighted average data fusion method that it demands high integrality of measurement data to measurement equipment, we proposed a real-time data fusion method based on multiple distance measurements of networked scout radars.Under least squares rule, the networking fusion model of scout radars was established, and the initial value choice of the parameters to be estimated, determination of weight coefficient matrix, and fusion precision were studied for model solution.The real-time performance and precision of the proposed method were verified through simulation and analysis.
