| Abstract: | One method of central frequency of main clutter accuracy tracking for the airborne fire control radar system is introduced.Central frequency of main clutter is estimated accurately using combined methods,including central frequency of main clutter inaccuracy tracking,interline ground speed correction and iterative repetition,in-frame distance to frequency correction of the main clutter,power spectrum estimation.Precision of the four methods estimating central frequency of main clutter is also discussed.The paper presents the results in engineering practice.This method has been successfully applied in STAP GMTI mode. |
