数据融合在双基地雷达抗冲击干扰中的应用

摘要

数据融合是信息处理的一个重要领域,并且随着双/多基地雷达研究的不断深入,多站间信息融合成为了研究的热点.传统的抗冲击干扰方法只是基于单基地高频雷达的雷电抑制,文中提出了一种针对双基地高频雷达的数据融合抗冲击干扰方法,在双站分别抗干扰的基础上利用信噪比最大数据融合原理进行双站信息去冗余.该方法能综合提取双站有用信息,在抑制冲击干扰的同时提高了目标检测概率与目标估值精度.%Data fusion technique is an important area of information processing.With the development of bis/multi-static HF radar,the data fusion of multi-station has become a hot topic.The traditional interference suppression method is only for monostatic HF Radar.A novel method based on data fusion algorithm is proposed to suppress burst interference in bistatic HF radar.On the basis of suppress burst interference in every monostatic,redundant information is excised by the data fusion method which is based on the ratio of signal to noise.The beneficial information of bistatic can be integrated completely by this method.And it can not only inhibit transient interference effectively,but also improve the estimation accuracy and the detection probability of target at the same time.
