adaptive line enhancer meaning in Chinese

自适应线增强器

Some techniques about adaptive line enhancer ( ale ) are introduced in this thesis , which are used in active sonar to improve its detection performance
本论文着重对自适应线谱增强器( ale )应用于主动声纳信号检测的问题进行研究，以期改善主动声纳的检测性能。
Based on advantages of sign algorithm and coherent integrator algorithm , a fast algorithm of foc sign coherent integrator based adaptive line enhancer is presented . this algorithm has better tracing feature , steady output , and low complexity
该算法充分利用了极性迭代算法与相干累积算法的优点，具有收敛速度快、系统稳定等西北了业人学博i ：学位论义特点。
The convergences of these algorithms are proved in theory . their output signal - to - noise ( snr ) is derived and bigger than that of the traditional adaptive line enhancer ( ale ) . simulation with the torpedo - radiated data indicates that the proposed algorithms are much better than the ale and the short - time correlation based adaptive line enhancer ( scbale ) in suppressing gaussian noise and enhancing spectrum feature
对该算法的收敛性能进行了严格的证明，推导了该算法输出信噪比的计算公式，证明了该信噪比总是大于基于lms的自适应线谱增强器的输出信噪比，定义了评价算法性能的若干参数。
