查询词典 representative domain

A kind of adaptive beamforming algorithm called the time-domain analysis minimum variance distortionless response is presented to improve the performance of frequency domain MVDR in the presence of fast-moving signal sources.

针对频域最小方差无失真响应方法在源方位快速变化情况下稳定性差的问题，提出了一种基于时域解析信号的MVDR自适应波束形成方法TAMVDR(Time-domain Aanlysis MVDR)。

The beamforming is an important measure of the orientation estimation in theunderwater sound positioning. The Generalized Correlation Beamformer isstudied and the algorithms of FIM and WFIM(WeightedFourier Integral Method) are given. In most circumstances, the performance of these two algorithms is better than Delay-Sum Beamformer. The MVDR(MinimumVariance Distortionless Response) adaptive beamformers are investigated in element andbeam domain. The research results show that the beam-domain MVDR algorithm notonly increases the resolution, but also saves computer when using it to aim orientationestimation.

4水下声定位中波束形成技术是方位估计的重要手段，重点研究了广义相关波束形成算法傅氏积分方法(FIM和加权傅氏积分方法，大多情况下FIM、WFIM算法的性能优于时延—求和波束形成；研究了阵元域和波束域MVDR自适应波束形成，结果表明，利用波束域MVDR进行目标方位估计，既可以获得高精度的方位估计，又可以大大减少计算量。
