13564 多通道回归分析法和双主成分分析法识别出的结果类似, 无论陆地和洋面还是冬季和夏季均可有效使用。 Meanwhile, both the multi-channel regression analysis method and the DPCA method have stronger applicability and are equally effective in both land and ocean or winter and summer.
13565 当10.65GHz和7.3GHz波段观测同时存在RFI时, 比值法将不能识别出10.65GHz的RFI信号, 并且比值法会将海陆边界及附近视场的观测误判为RFI信号。 When the RFI exists simultaneously in 7.3GHz and 10.65GHz channel observations, the ratio method will not recognize the RFI signal of the 10.65GHz.On the ocean surface, the ratio method will misjudge the observation of the sea-land boundary and nearby field of view into RFI.
13566 多通道回归分析法和双主成分分析法的适用范围较为广泛, 而谱差法和比值法各有弊端。 In short, both the multi-channel regression analysis method and the DPCA method have a wide range of applications, but the spectral difference method and the ratio method have their own drawbacks.
13567 在平面近场天线测量中, 有限扫描面截断是影响测量精度的主要误差源之一, 找到解决截断误差的方法是天线测量的研究重点之一。 In planar near-field antenna measurements, finite scanning plane truncation is one of the main reasons which cause measurement error, therefore, the key point is to find a solution to solve the truncation error.
13568 文中将平面近场天线测量中由有限区域内的场求平面波谱的过程抽象为带限函数外推的数学模型, 从实际测量中的近远场变换理论出发, 论证了GP (Gerchberg-Papoulis) 算法应用在平面近场测量中在理论上是切实可行的。 The process of solving the plane wave spectrum from a finite field in planar near-field measurements is abstracted as a mathematical model for the band-limited function extrapolation, and it is proved that Gerchberg-Papoulis (GP) algorithm applicated in planar near-field antenna measurements is feasible, which is based on nearfield to farfield transform theory in actual measurements.
13569 将GP算法应用在平面近场天线测量中, 并分析了不同迭代次数算法的修正情况。 This paper introduces the GP algorithm in planar near-field antenna measurement, and the effect of algorithm with different iterations is also analyzed.
13570 结果表明, 随着算法迭代次数的增多, 可信角域外计算方向图与理论方向图差别明显减小。 The results show that the differences between deduced pattern and theoretical pattern decreased significantly out of reliable angle region with the iterative number of algorithm increase.
13571 因此, 本文的方法能够明显减小平面近场测量中截断误差的影响。 Therefore, the method introduced in this paper can significantly reduce the truncation error.
13572 除此以外, 还分析了误差对算法收敛性的影响, 结果表明, 误差对算法修正效果影响较大。 Moreover, the influences of algorithm convergence brought by errors are also analyzed, the results show that the effect of the algorithm was influenced by errors greatly.
13573 详细研究了环圈结构的高频特性和返波振荡特性。 In this paper, the high frequency characteristics and backward-wave oscillation characteristics of the ring-loop structure are studied in detail.
