Abstract：Pulse Doppler（PD） radar seekers face the issue of degraded tracking and guidance accuracy when confronted with highly maneuverable targets employing velocity gate pul-off（VGPO） jamming.To address this，ananti-VGPO algorithm based on interacting multiple model（IMM） probabilitydata association（PDA） is proposed，specifically tailored forair-to-air/air-to-ground misile applications.This algorithm combines the strengths of PDA and IMM，utilizing PDA filters to process measurement information from angle and velocity channels，while incorporating an IMM framework to dynamically adapt to the target motion paterns under various maneuvering states.Simulation experiments demonstrate that the proposed anti-jamming algorithm enhances the capability to capture complex maneuvering behaviors and improves the robustness of target state estimation.Simultaneously，iteffctively mitigates the impact ofvelocitypulloffjamming and enhances the missile guidance accuracy.
