摘要
在声纳搜索水雷任务中,为提高剩余雷数估计的准确性,加强作战辅助决策能力,针对现有评估模型未考虑漏搜区和重叠区,评估结果误差和离散性较大的问题,提出一种修正发现雷数的方法:对任务区建立网格,根据记录航迹获得的覆盖次数分布情况,从中提取出漏搜信息,并用其修正发现雷数向量。该方法有效解决了评估向量误差大、维数偏低的缺陷,显著提高了合理性。对典型情况的大量仿真试验证明,该方法能大幅度提高评估结果的准确性,降低离散性,并具有更强的适应性。
In the task of sonar＇s searching mines,in order to improve the evaluation accuracy of the remained mines and enhance the assistant decision-making capability of operations,owing to the fact that the existing evaluation models do not take holiday and overlapping areas into consideration,and that there is great evaluation errors and discreteness,this essay puts forward a method of revising the number of mines detected.Adopting grid analysis,the number of runs in the task area can be obtained based on the track records,from which the holiday information is obtained.The holiday information can help revise the vector of number of mines detected,and thus effectively solve the problem that the errors of evaluation vector are big and the dimensions are few,the result of which will be remarkably more reasonable.Large numbers of simulation experiments for the typical cases prove that this method can greatly improve the evaluation accuracy,reduce discreteness,and have better adaptability.
