基于遗传算法的潜艇自航模水声定位系统定位站布置研究

根据自航模试验中水声定位系统遇到的具体问题,抽象出了三种优化模型,并且提出了衡量特定阵型定位精度的目标函数,编制了适用于该优化模型的遗传算法程序,通过优化模型Ⅰ验证了该程序的正确性。此后,利用该程序分别计算出了模型Ⅱ、Ⅲ定位站最佳布置位置,得出水下布防2个水听器形成十字阵为最佳布阵型式这一结论,总结出新的布阵方法,即在岸边先选取距离尽量远的两个点布防水听器,之后在两点连线的中垂线附近布防两个水下水听器,具体位置可以通过遗传算法算出。

Optimization on acoustic receivers' arrangement in submarine self-propelled model test with genetic algorithm

Three optimization models were proposed according to the problems emerged from self-propelled model test.And the object function to evaluate acoustic positioning’s precision of some given receiver’s ar-rays was created.The genetic algorithm code to solve this optimization problem was developed and validat-ed by optimization modelⅠafterwards.The optimum arrangements for models Ⅱand Ⅲ were acquired by cal-culating such code.The cross arrays was certificated to be the optimum ones.One new method to arrange acoustic receivers in self-propelled model test was drafted.
