基于匹配场的多目标源定位研究

Multi-target localization based on matched-field

为了研究匹配场定位方法对多元目标的定位效果,使用简正波模型运用匹配场处理进行三目标源定位模拟,对声场进行向量表示,并分别采用常规匹配场处理方法和功率定律处理方法进行匹配处理,分别对单目标和多目标进行仿真,做了多组不同信噪比和不同匹配方法的仿真结果,并进行分析和比较。仿真结果表明,采用匹配场定位的方法对多元目标定位同样有着良好的定位效果。

In order to study the effect of multiple target location using matched field processing,this article uses the normal mode model using match field processing to do a three-goal localization simulation.The sound field represented as a vector,using conventional methods and the law of approach to match the power handling.Respectively,for single-objective and multi-objective simulation,made a number of different groups and different signal to noise ratio matching the simulation results,and analysis and comparison.Simulation results show that the use of matched field methods for multi-location targeting the same positioning with good results.
