Grey Cutting Variable Dimension Filter of Maneuver Target Tracking

An algorithm for grey cutting variable dimension filter to track a maneuver target based on grey prediction filter and cutting variable dimension filter is developed. Grey prediction filter buried in cutting variable dimension filter with superior algorithm on maneuver detection as a switch, cutting variable dimension filter is taken the place of grey prediction filter in the maneuver region and the former is guided by the latter in this region. This method has an excellent adaptability to the environment changes and highter accuracy, hence its priority over both analogues of filter algorithm mentioned above. In grey cutting variable dimension filter terms, there is no need of any statistic parameter. The computer simulation shows its superiorities.
