水声被动交叉定位算法应用研究

Applicaion of Passive Sonar BearingCross Location Algorithm

文章通过双基阵被动测距的方位交叉定位法,自动计算水声源前端测得所有方位目标的交叉点,并对交叉点进行历史点管理。通过交叉点形成的轨迹的连续性和平滑性判定产生交叉点的原始方位目标是否是同一个目标。在多站多基阵的环境下,验证了该算法的有效性和可行性,该方法可以成为纯方位目标同一性认定的有效手段。最后,对交叉定位法在实际工程应用中遇到的问题进行了总结,并指出了不足之处,以待后期进一步完善。

By Bi‐static array passive ranging bearing cross location method ,the paper automatically calculates all bear‐ing target cross location point measured by the front sound source ,and manages the historical cross location point .The con‐tinuity and smoothness of the track formed by cross location point are used to determine the bearing target form the same source .Under a multi‐station multi‐array environment ,the effectiveness and feasibility of this algorithm are demonstrated , which can become effective means of identification of same target .Finally ,this paper summarizes development problems in the process of practical application and points out the shortcomings .
