Study on data fusion algorithm of radar and IRI

In modern war, the war field enviorment is complex and interfere is heavy, single mode weapon can not meet the army need, multi-mode guiding weapon can take advantage their merits, and its core is multisensor data fusion. Radar and IRI sensor data fusion algorithm is studied in this paper, and the data fusion algorithm is given in this case. The observed data is fused by using weighted least square, and the estimatation result data is fitted with the data that get in former time to obtain the result at this moment. The information of the every sensor is taken full advantage, and the well effect is gained.
