【摘要】 根据多基地声呐系统的特点,研究了用单纯基于声波到达时间(TOL)算法进行水下目标定位的原理和误差分布。通过数值仿真,给出了用多基地TOL算法进行水下目标定位,误差几何分布的等值线图。仿真结果表明,用多基地声呐系统进行水下目标定位,比同等条件下单/双基地声呐定位,具有更高的定位精度。更多还原

【Abstract】 Based on the character of multistatic sonar, the location principle and estimating error of timeonlylocalization (TOL) algorithm are studied in this paper. Through simulation, the Geometrical Distribution of Precision (GDOP) for multistatic sonar is given. The simulating results show that the location accuracy of multistatic sonar is higher than that of monostatic sonar.更多还原
