摘要:

脉冲多普勒雷达导引头面对释放速度拖引干扰的强机动性目标时, 存在跟踪、制导精度下降的问题。为此, 结合空空/地空导弹应用场景, 提出一种基于交互式多模型概率数据关联的抗速度拖引干扰算法。该算法结合概率数据关联和多模型交互的优势, 采用概率数据关联滤波器处理角度和速度通道的量测信息, 同时引入多模型交互框架动态适应目标在不同机动状态下的运动模式。仿真实验表明, 提出的抗干扰算法可增强对复杂机动行为的捕捉能力和目标状态估计的鲁棒性, 有效降低速度拖引干扰带来的影响, 提升导弹制导精度。

Abstract:

Pulse Doppler (PD) radar seekers face the issue of degraded tracking and guidance accuracy when confronted with highly maneuverable targets employing velocity gate pull-off (VGPO) jamming. To address this, an anti-VGPO algorithm based on interacting multiple model (IMM) probability data association (PDA) is proposed, specifically tailored for air-to-air/air-to-ground missile 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 patterns 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, it effectively mitigates the impact of velocity pull-off jamming and enhances the missile guidance accuracy.

Key words: highly maneuverable target tracking, velocity gate pull-off (VGPO) jamming, interacting multiple model (IMM), probability data association (PDA)
