摘　　要：研究了多基地声纳定位中的椭圆交叉定位与双曲线交叉定位方法,由公式推导分析了输入误差对两种定位结果的影响,给出了误差放大因子的定义,通过计算机仿真,比较了不同站位分置距离下,误差放大因子的变化情况。同时,在相同阵型配置下,对比了椭圆交叉定位与双曲线交叉定位的优劣。结果表明,增大多基地各站址的分置距离,可以扩大具有较好定位精度的区域。The eliptic and hyperbolic cross ifxes in the multistatic sonar localization method is studied. By the formula derivation, the effect of input errors on the two positioning results is analyzed. We proposed the deifnition of the error magniifcation factor, and compared the variety of error magniifcation factor for the same pattern conifguration but different separation distances by the simulation. Also the performance of the cross ifxes between eliptic and hyperbolic is researched. The results indicate that the area where the error magniifcation factor is smal can be enlarged by increasing the separation distance.
