Most radar signals are non - stationary signals , but they are cyclostationary signals , namely , the correlation function of radar signals is periodic function of time 大部分的雷达信号都是非平稳信号,但它们都具有循环平稳特性,所谓循环平稳信号是指相关函数为时间的周期函数的一大类非平稳信号。
Chapter 5 is detailed to discuss the produced principle , correlation function and application of gold code . from several aspects , the chapter studied the balanced gold code in - depenth 第五章详细讨论了gold码的产生原理、相关函数及其应用，对性能优越的平衡gold码从不同方面进行了深入的研究。
Especially , the dft approach only needs a second order direct correlation function ( dcf ) of the coexistence bulk fluid as input , and is therefore applicable to the subcritical temperature region 特别是密度泛函近似仅仅需要共存体相流体的二阶直接相关函数作为输入，因而可以应用于超临界与亚临界温度。
At same time , it was also investigated the impact of the position errors of multiple antennas both sides of transmit and receive on the correlation of antenna array , and the simulation results by computer are also given 同时还研究了多天线的位置误差对天线阵列的相关函数的影响，给出了有关仿真结果。
Firstly , from the viewpoint of graph theory , we analyzed fitness landscapes , and described the random walk correlation function , then we deduced the equation to compute the correlation length 从图论的角度对遗传算法适应值曲面进行了分析，描述了适应值曲面上的随机游走相关函数，详细推导了相关长度计算公式。
The time - domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ) , capturing virtually all of the signal but rejecting most of the noise 对相关函数进行时域滤波，挑选出互相关函数中窄信号自相关函数部分，去掉剩余的大部分噪声能量，得到加窗互相关函数（ ccf ） 。
We analyzed its nature of resolving coherent sources and compared the influence of different focusing matrices . simulations are conducted to test the performance of these focusing matrices . 4 分析了cssm方法分辨相干源的实质，即通过频域平均消除了相关函数矩阵的奇异性；分析比较了几种不同聚焦矩阵对算法性能的影响。
Most of the time , it makes sense to package the functionality of routines that perform related functions within the same assembly , especially if these routines share classes whose methods call one another 在大部分时间里，打包在同一程序集中执行相关函数的例程的功能才有意义，如果这些例程共享相互调用方法的类，则尤为如此。
The theory and the method are validated by the simulational experiments , in which the scattering from random self - affme fractal surface are simulated and the speckle intensity correlation function are calculated 我们通过模拟实验，并以自仿射分形随机表面附近散斑光强的相关函数进行数值计算为例，对该理论和方法进行了验证。
Several coregistration methods are dissected and compared , which include correlation - based algorithm and maximum spectra algorithm . following , the flat effect analysis and removal in insar imaging are dissertated 比较分析了最大相关函数法和最大谱配准法两种配准方法,论述了平地效应产生的原因以及去除平地相位给信号处理带来的好处。
