空间频率响应 meaning in Chinese

spatial frequency response

Computer simulation results show that the beamspace wsf algorithm retains the super performance of its element space counterpart when applied to the beam outputs of some practical acoustic - receiving array . 3 . an improved form of classical time domain broadband beamforming is proposed by combining digital delay lines and fir filters
提出了对经典时域宽带波束形成器的改进方法，采用数字延迟线和fir数字滤波器结合的方式实现时域波束形成，以消除波束畸变并实时实现结构特殊的空间频率响应。
It shows that a disadvantag ekists when a crsi is used to measure a step structure in a wavefront , but it is useful to adjust a crsi system with lcslm . 4 . according to the didriction effect of an aperture , the spatial resolution of our crsi was analyzed and the transform function of our crsi was calibrated by using the psd method of a step wavefront . and some factors which are associated with the accuracy of our crsi were analyzed too
四、从光学系统衍射效应的角度分析了本文建立的环路径向剪切干涉仪的空间分辨率，并利用波前功率谱密度的概念对该干涉仪的空间频率响应特性进行了标定，分析了限制该干涉仪测量精度的主要因素以及径向剪切比与测量精度的关系，并指出了该干涉仪的测量范围，结果显示该干涉仪基本上可用于准确测量中低频段的波前畸变。
