aperture synthesis meaning in Chinese
孔径综合法
口径的合成
综合孔径
Examples
- One is the optimizing of the distribution of receiving elements ; the other is the image retrieving algorithm . the results of numerical simulations and field experiments show that the theory of aperture synthesis is feasible
通过数值模拟完成了一维和二维情况下多种空间频率采样的机理论证，通过对西安市闫良机载实验数据的处理分析，有力的说明了孔径综合理论的有效性。 - Aperture synthesis uses interferometry technique to improve the limitations set by antenna physical aperture while working at lower frequency . phase and amplitude calibration of the visibility samples must be carried out to compensate for system bias before measurement
综合孔径技术利用了以小口径天线阵列合成大的观测口径的技术，解决了在较低频率时天线物理口径要足够大才能得到期望的空间分辨率的严重缺陷。 - Aperture synthesis sonar , as its name implies , synthesizes an aperture by storing successive echoes obtained from a moving platform and by processing the results as if they had been obtained from a multi - element array enables a high azimuth resolution to be obtained from a physically small array
合成孔径声纳，顾名思义就是通过小孔径物理声阵的匀速直线运动，将沿航迹方向的回波数据相干累加，形成较大的虚拟孔径，从而提高方位分辨率。合成孔径技术相对于常规声纳技术的突出优势在于，它只利用小孔径的物理声阵，就可以得到与径向距离和频率都无关的高方位分辨率。 - Topics covered include : statistical analysis of signal processing systems , including radiometers , spectrometers , interferometers , and digital correlation systems ; matched filters and ambiguity functions ; communications channel performance ; measurement of random electromagnetic fields , angular filtering properties of antennas , interferometers , and aperture synthesis systems ; and radiative transfer and parameter estimation
