摘要
为了实现对海中航空搜潜浮标位置的定位,进行了三方面的研究工作,其一以反潜机的位置、运动路径、反潜机与航空搜潜浮标的相对位置和距离关系为依据,利用斜距测量法,分析了计算搜潜浮标位置的原理和方法;其二采用最小二乘法,建立了反潜机对浮标定位的数学模型及相应的快速定位算法;其三仿真分析了初始估计角对计算浮标位置收敛速度的影响,并对定位算法进行了验证.仿真结果表明所用算法能够达到快速收敛的目的.
In order to calculate the anti-submarine sonar-buoy position, three aspects research work have been done. First, based on the relation between anti-submarine plane position, moving path, relative position and distance which between plane and anti-submarine sonar-buoy, the slant range measurement method is used to analyze and calculate sonar-buoy position, second, the least squares method is used to establish the sonar-buoy location mathematic model and speediness location algorithm, third, the influence about original estimation angle to the calculation sonar-buoy position convergence speed is simulated and analyzed, and the simulation result show that the location algorithm is speediness convergence.
