Data Fusion Algorithm for Measurement of Multiple Equipments on Maritime Mobile Tracking Stations

In order to improve the accuracy of outer-trajectory measurement data processing, appropriate methods should be selected according to the features and demands of different missions. Based on the engineering background of space tracking ships' multiple equipments tracking the same flying object during precision evaluation test at sea, we first propose the concept of measurement data fusion, according to the principle of which discuss the application of data fusion technology; then we present several algorithms for target position data fusion, at the same time process the measurement data with weighted least square fusion algorithm. Engineering application results show: Data fusion method discussed in this paper possesses such features as fewer calculations, higher precision and adaptable to project application.
