【摘要】 通过仿真试验分析了ICCP算法和TERCOM算法应用在水下地形匹配中的优点和不足,在此基础上,研究了两种组合匹配算法:1)用TERCOM算法作预匹配,并将TERCOM算法中的MSD相关性指标引入ICCP算法中作为ICCP算法的防误匹配机制,以提高匹配精度,这种组合适用于初始误差中平移分量大的情况;2)用ICCP算法解决旋转偏差后再转入TERCOM算法,这种组合适用于初始误差中旋转分量大的情况;仿真结果表明,组合算法有利于提高鲁棒性和快速性。更多还原

【Abstract】 The advantage and disadvantage of ICCP and TERCOM being used in underwater terrain match are analyzed by simulation.Two assembled algorithms are studied: 1) uses TERCOM to get over the problem caused by the large error of the preliminary position,and then finish the left through ICCP;and the matching rule-mean square difference(MSD) in TERCOM is applied as preventing miss-matching rule in the ICCP.2) uses ICCP to figure out the orientational error first,then finish the left by TERCOM.The simulation results show that assembled algorithms have more robustness and speediness.更多还原
