look direction meaning in Chinese
探视方向
Examples
- Usually these pole extraction methods are poor when the value of the residual corresponding to the pole is small . in order to avoid the disadvantages , the matrix pencil method for the pole extraction of transient responses from multiple look direction is introduced
针对大部分算法由于入射方向的不同而导致目标的某些极点由于留数太小提取不出来的缺点,采用了一种使用多个入射方向瞬态响应的矩阵束法来提取极点。 - The wsf method and ml method can be used in direction finding of coherent sources . we find that tam has the widest direction finding range while the available direction finding ranges of the dsam , sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp are in a certain area centered at the look direction . the sam _ isp , sam _ aisp , sam _ gsp and sam _ agsp can change the effective direction finding ranges by adjusting their inner parameters and furthermore they can improve the sidelobe suppression effect compared with the dsam method
得到tam的测向范围最宽,基于后五种简化阵列流形的测向方法其测向有效范围均是集中在波束指向附近的一定范围内,其中sam _ isp 、 sam _ aisp 、 sam _ gsp和sam _ agsp对应的测向范围可通过调整内部的参数进行相应的调整,相应地较dsam也可改善对旁瓣源的抑制效果。 - In chapter 4 , a chebyshev method beamforming for uniform circular arrays ( ucas ) is proposed based on dolph - chebyshev method for uniform linear arrays ( ulas ) . this method is that it computationally efficient which makes it eminently suitable for real - time beamforming and beamstearing applications . we describe the new approach for synthesizing array patterns with guaranteed least sidelobe levels for any look direction
我们对基于均匀线阵dolph - chebyshev波束合成方法进行研究，提出了基于均匀圆阵dolph - chebyshev波束合成算法，即期望信号在任意入射角度时，均能保证同样的主瓣宽度和最小旁瓣电平的阵列方向图合成算法。
