Abstract: Fo r the t rack ing of m aneuvering target s, an on2line adap t ive w eigh ted fu sion algo rithm fo r m u lt i2sen so r data is p resen ted. The algo rithm can adju st the fu sed sen so r’s w eigh t acco rding to changes in the sen so r’s variance, and the est im at ion erro r is kep t as of least m ean square. The algo rithm can adap t it self to the changes of sen so r’s character. Compu ter sim u lat ion resu lt s indi2 cate that the t rack ing algo rithm is very po ten t ial in p ract ical engineering system s.
