多路径效应对舰载自卫干扰效能的影响

Influence of Multipath Effect on Shipboard Self-protection Jamming Effectiveness

考虑海面多路径效应,建立舰载有源自卫干扰压制区模型,定义了跟踪误差干扰度,用来衡量多路径效应下舰载有源自卫干扰对反舰导弹末制导雷达的干扰效能,考虑海杂波的影响,选取适当指标衡量舰载箔条质心干扰的干扰效能,并以舰载有源自卫干扰效能评估为基础,分析了多路径效应下有源无源复合干扰的干扰效能,通过示例,验证了模型的有效性。

Considering the multipath effect of sea surface,this paper sets up the model of shipboard active self-protection jamming blanketed zone, defines the tracking error interference degree to measure the jamming effectiveness of shipboard active self-protection jamming to the terminal guid- ance radar of anti-ship missile under multipath effect, considering the influence of sea clutter, se- lects appropriate index to measure the jamming effectiveness of shipboard chaff centroid jamming; and taking shipboard active self-protection jamming effectiveness evaluation as the foundation, ana- lyzes the jamming effectiveness of active/passive complex jamming under multipath effect, validates the validity of the model through an example.
