摘要
单舰双基地声纳对鱼雷目标进行定位时,由于基线较短,测向信息(DOA)误差较大,系统对目标的定位精度不足。提出一种以双基地声纳测向信息为观测量的卡尔曼滤波定位算法,并进行理论推导和仿真计算。仿真结果表明:相比于传统交叉定位算法,该算法可将双基地声纳系统对来袭鱼雷的定位精度提高37%(0.13R)。
When single-vessel bistatic sonar is used to locate torpedo,the target positioning ac-curacy is insufficient due to the baseline shortage and DOA error.A Kalman filter localization al-gorithm based on DOA information is proposed,after theoretical derivation and simulation,the re-sults show that,compared with traditional cross location algorithm,the positioning accuracy of the incoming torpedo with the proposed algorithm is improved by 37%(0.13R).
