摘　　要：针对水声环境参数传统获取方法的缺点及其在非常时期或非合作海域不易获取的情况,提出了水声环境参数盲估计的概念及理论模型,通过对目标函数的选取,采用遗传算法对多个水声环境参数和未知目标的空间位置进行全局寻优,并依此对基于不同信噪比观测数据的水声环境参数盲估计进行了计算机仿真。水声环境参数盲估计的仿真算例表明,水声环境参数盲估计技术是可行和有效的。The concept and theory model on blind estimation of environmental parameters on underwater acoustic were presented because the traditional measure of acquiring environmental parameters on underwater acoustic was disadvantage and it was hardly acquired during unconventionality or on uncooperative sea. By choosing objective function and adopting genetic algorithms, environmental parameters on underwater acoustic and acoustic source position were searched. Meanwhile, the simulation of blind estimation of ocean environmental parameters was carried out based on various SNR observation data. The simulation result shows that the blind estimation technique of environmental parameters on underwater acoustic is feasible and effective.
