应用背景近年来，预条件迭代法因为可以很好的解决迭代时解的收敛速度非常缓慢这一情况，越来越受到很多学者的关注，不同的预条件矩阵的解的收敛速度影响也不同，众多学者试图找到更优的预条件矩阵。 关键技术包含了GAOR、GMTS以及MAOR三种预条件迭代法的数值算例程序，可以按照自己的预条件矩阵进行修改，给定参数值，运行便可得到未预条件和预条件迭代矩阵的谱半径值。

由于显卡或者显示器的原因会出现实际输出的图像在亮度上有偏差，而Gamma曲线矫正就是通过一定的方法来矫正图像的这种偏差的方法.(Or because of the graphics display image will appear in the actual brightness of the output deviation, the Gamma correction curve is corrected by a certain method to the method of this bias image.)

说明：  复杂环境中的微弱目标（如隐身飞机、被地/海/城市杂波淹没的目标等）探测 问题是现代雷达面临的严峻挑战。 与传统的先检测后跟踪（ DBT） 技术相比， 检 测前跟踪（TBD）技术是一种新兴的先进信号处理技术，它通过多帧回波数据积 累和联合处理，可以显著提高雷达的微弱目标检测跟踪性能， 是国际雷达界研究 的前沿热点。 TBD 作为一项正在发展中的新技术，还需要解决一些新的技术问题， 例如， 多目标跟踪维数灾难、临近目标相互干扰等，以及处理难度增加和运算量 增大带来的新问题。(The detection and tracking of low observable targets (e.g. stealth targets, targets buried in strong clutter) in complex environment are great challenges for modern radar systems. Different from the traditional detect-before-track (DBT) methods, Track-before-detect (TBD) is a novel and efficient signal processing method which is proposed in recent years to detect low observable targets, and has got much attention internationally in radar research area. By jointly processing several data frames, TBD is able to produce more reliable detection and tracking results. As a developing new technique, TBD has its own problems and challenges.
