基于DBSCAN算法的PDW数据二次分选方法研究
|
摘要
雷达侦察装备通常只对PDW数据进行一次分选,从而形成雷达目标。以DBSCAN算法为核心,提出对PDW数据二次分选的流程。这种方法实现了对第一次分选过程中被认为没有价值的,应该丢弃的PDW数据的再次分选。仿真结果表明该方法具有可行性,一定条件下能够降低雷达侦察装备对微弱雷达信号的漏警。
A radar reconnaissance equipment usually performs the first sorting to pulse description word(PDW)data in order to form radar targets.This paper takes DBSCAN algorithm as the core,and proposes a second sorting process to PDW data.This method realizes the second sorting to the PDW data which is considered worthless and should be thrown away after the first sorting.The simulation results shows that the method has feasibility and can reduce the missing alarm probability of a radar reconnaissance equipment to the weak radar signal under a certain condition.
