Detecting of anti-radiation missile by applying changeable-sample ratios technology in the AEW system

Changeable-sample ratios technology is applied to detecting an anti-radiation missile in the AEW (airborne early warning) system. First, we analyze the signal model and, when it is in the active flight time and in the passive flight time respectively, we use special processing methods. At the same time, the AEW tracking process of the antiradiation missiles is analyzed. Finally, the simulation experiment is also given. The simulation results show that in AEW system, anti-radiation missiles can be detected effectively by changeable-sample ratios technology.
