接着建立了舷外干扰模型，包括箔条干扰模型和拖曳式有源诱饵模型。

And then, chaff jamming and towed active decoy models are built, which are included in the off-board jamming model.

传统的拖曳式雷达有源诱饵对抗导引头跟踪系统，其干扰效能受到限制。

When traditional towed radar active decoy (trad) is against a missile seeker system, the jamming efficiency is restricted.

介绍了机载拖曳式有源雷达诱饵对PD雷达的干扰原理和系统结构，并分析了诱饵的工作过程，重点对其关键参数进行了研究和仿真。

TRAD and its interference principle on PD radars is introduced, and jamming procedures of the decoys are analyzed. The key parameters of TRAD are detailed studied and simulated.
