摘　　要：通过对多声纳基阵二维目标联合测时差定位算法及精度分析,给出系统具体的定位公式和误差计算公式,对不同基阵布阵形式下的目标GDOP分布情况和基线等对GDOP的影响进行了仿真分析。结果表明,定位误差与目标和基阵的位置、测时差误差等有关,基阵布阵形式不同,误差分布也不同。The two-dimension s target joint location and accuracy based on time of arrival measurement in,multiple sonar arrays are analysed in this paper.Then,the concrete location formulas and error calculating formulas in the location system are presented,and the contours of GDOP with different distribution of the arrays and basic line are drawn by computer simulation.The result shows that the location errors are influenced with target and basic arrays s postion and timing errors and so on.And if the distribution o...
