鉴于此，对距离波门拖引干扰效果评估进行了研究。

So the effectiveness evaluation of Range Gate Pull Off (RGPO) is studied in this paper.

距离-速度同步拖引干扰是对抗PD雷达的有效方法。

Range-velocity simultaneous pull-off is one of effective measures for countering PD radars.

然后对舰载有源干扰进行了建模，包括噪声压制干扰模型和距离拖引干扰模型；

Firstly it establishes the model of the anti-ship missile radar seeker. Secondly it builds active jamming models, including noise suppressing jamming model and Range Gate Pull Off (RGPO) model.
