Example Sentences:

	1.	The most important feature of phase - only nulling method lies in only making use of phase perturbations for controlling pattern ' s nulls , namely , amplitude of weights is fixed 唯相位( phase - only )方向图置零方法是一种只利用阵列单元的相位扰动对方向图的零点进行控制的波束形成方法。
	2.	Phase - only . nulling method is not only applied to reception pattern but also radiation pattern . however , this method only uses information of weights so that equations for defining phase perturbations are generally unlinear 由于这种方法只利用了权系数的相位信息，确定相位扰动(或权系数)的方程组一般都是非线性方程组，求解比较困难。
	3.	To correct these effects , two methods were introduced in this paper : using weighted function to constrain second phase error caused by dispersion , and utilizing pga algorithm to reduce the phase perturbation due to the irregularities of the ionosphere 本论文介绍了两种校正方法：利用加权函数抑制色散效应引起的二次相位误差，以及使用相位梯度自聚焦算法较正由电离层的不规则性引起的信号相位起伏。
	4.	On the following , on the basis of formulas given above , three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last , the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution 文中主要研究了电离层的三种影响：信号经过电离层传播的群延迟引起的成像偏移；电离层的色散效应给线性调频信号带来二次相位误差，导致图像退化、失真；以及电离层的闪烁、湍流等不规则性引起的信号相位起伏。在此基础上，比较分析了不同波段、带宽条件下电离层的影响。
	5.
