针对普通水平双三角阵定位精度较差的问题，提出了一种带水平倾角的被动声定位双三角阵模型。该模型与水平双三角阵的区别在与三角基阵带有水平倾角，并且模型各项参数也得到了进一步地优化。仿真计算结果表明：当基阵臂长(等边三角形边长)为0.2 m、基阵间距(两三角形最近顶点距离)为1.6 m及等边三角形与水平面的夹角(水平倾角)为75°时，双三角阵的测试精度较优且能在10 m×10 m的有效靶面内，使得各向测量误差均控制在±1.2 cm以内，且误差跳动量小。

This paper presents a kind of double triangle array model with horizontal sextant angle at the problem of low precision of horizontal double triangle array. This model has a biggest distinguish with horizontal double triangle array is the horizontal sextant angle,and its parameters were further optimized. Simulation results show that the test effect of the double triangle array with basic array arm(equilateral triangle side length)as 0.2m and the two basic arrays spacing(the two triangles nearest vertex distance)as 1.6m is quite better,as the angle be-tween horizontal plane with equilateral triangle (horizontal sextant angle)is 75 degrees. The sensors array mod-el can make the measurement error less than 1.2cm within 10m×10m effective target area,and the error jump variables is stable.
