Abstract

A computer implemented data distribution method for radar data. The method first receives distribution groups. Each distribution group corresponds to a data storage terminal and includes source code corresponding to data collection terminals. Next, the method calculates distances between the data storage terminals and the data collection terminals and selects the source code in the distribution groups with a shortest distance. In the previous comparison, if the priority levels of the source code are the same, distances between the data storage terminals and the data collection terminal corresponding to the repeated source code are calculated. The source code is selected for a distribution group which has the shortest distance. The steps are repeated until the source code is all selected.
