| 摘 要： | 在水声信号盲分离技术仿真研究中，需要评价算法的收敛速度，稳态误差等，文中分析了水声基阵接收信号的实数延时模型和复数混合模型，提出了水声信号盲分离算法性能评价准则。该准则分为基于混合基阵和信号估计两种，在三／四元均匀线列阵上，盲分离实测非高斯舰船辐射噪声，分别用CRLS，CACY，EASI，CMA，MKMA算法通信班下了提出的算法评价准则，同时还给出了这些算法分离水声信号的性能曲线。

| Abstract: | In computer simulation for blind signal separation, we need to evaluate the separating algorithms, for example, convergence rate, steady state error, and so on. According the real domain algorithms, we present the evaluating criterion to the complex algorithms for blind underwater acoustic signals separation. The criterion is divided into two parts based on mixing matrix and source signals. RLS, ACY, EASI, CMA, MKMA algorithms are used to separate the non Gaussian ship noises recorded in computer simulation with 3/4 elements uniformly linear array. The simulation curves are given. Comparing several criterions based mixing matrix estimation, we present the optimal criterion. |
