A Study on the Influence Between Station Distribution of Netted Radar System and Data Fusion Accuracy
Peng Kang · Modern Radar · 2010
A structure and mathematics model on the station distribution of netted radar system is established. For researching the dimensional distribution state of the target localization precision in the radar net, the mathematics model of the netted radar geometric dilution of precision (GDOP) is introduced, and the localization precision distribution in straight air lines about the station distribution of netted radar system is described using netted radar GDOP, then the target data precision in straight air lines is computed using the simple least mean square (LMS) data fusion algorithm, and the corresponding relation between the evaluation measurement and data fusion accuracy of the station distribution is given. So it is proved that we can use GDOP to show the line data fusion precision in definite station geometric distribution. Then a practice example is illustrated.
