共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。 在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。(Conjugate gradient method (Conjugate Gradient) is between the steepest descent method between the method and Newton' s method, it takes only a first derivative information, but to overcome the steepest descent method convergence slow shortcomings, but also to avoid the Newton method needs to be stored Hesse and disadvantages of computing inverse matrix and the conjugate gradient method is not only one of the most useful methods to solve large linear equations, solution of large-scale nonlinear optimization is one of the most effective algorithm. In various optimization algorithm, conjugate gradient method is a very important one. The advantage is that a small amount of memory required, with step convergence, high stability, and does not require any external parameters.)

应用背景他的主要特点为从噪声中将所需要的周期信号的特征以功率谱的形式表征出来，通过设置合适的阈值可以代表目标。调频信号则是典型的脉冲压缩信号，其扩频特性使得其不易受噪声干扰关键技术%%  test the compressing characters of the chirp%%  TestChirpCompression周期图法的优点是能应用离散傅里叶变换的快速算法来进行估值。对利用式(1)、(2)得到的功率谱估值进行傅里叶反变换，可以得到信号的自相关函数估值。这种方法适用于长信号序列的情况，在有足够的序列长度时，应用改进的周期图法，可以得到较好的功率谱估值，因而应用很广。
