说明：  c自理阿婆；了解了解顾客了 快乐 噶爱国 (c self grandmother learn about customer happiness Karma patriotic)

张澄波的综合孔径雷达比较老的版本,但是很基础,逻辑简单明了(Zhang Chengbo of synthetic aperture radar older version, but it is based on simple logic)

分数阶傅里叶变换计算方面,线性调频脉冲压缩的Matlab程序,包含收发两个客户端程序。( Fractional Fourier transform computing, LFM pulse compression of the Matlab program, Transceiver contains two client programs.)

pca分类程序，主要用于脑电信号的分类。具有较好的分类精度！(pca classification procedures, mainly for the classification of EEG signals. Has better classification accuracy!)

vc++下各种数字滤波器的实验程序，包括带通，带阻，低通，高通。(vc++ a variety of digital filters under the experimental procedures, including band-pass, band stop, low-pass, high pass.)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)

地球物理勘探中，基础的地震波正演模拟程序，包括五个正演程序，（高阶中心差分，高阶交错网格差分，使用标准的PML边界的正演程序）在acou文件夹下附有运行的结果。(Geophysical exploration, based on the seismic forward modeling program, including the five forward procedure, (higher-order central difference, higher order differential staggered grid, using standard PML boundaries forward procedure) in a file folder with acou results of operations.)

关于紫外光语音通信系统的大气信道的仿真程序（MATLAB实现）(UV-voice communications systems on the atmospheric channel simulation program (MATLAB implementation))

详细讲述了直接序列扩频差分锁相环的文章，包含具体的算法结构，并附有仿真结果。(A novel differentially coherent delay-locked loop(DCDLL) for accurate code tracking is proposed for direct sequence spread spectrum systems. Due to the use of the differential decoder and exactly one correlator, the proposed scheme avoids the problems of gain imbalance. The tracking error variance is derived by linear analysis. When the proposed DCDLL scheme is applied in ranging with additive white Gaussian noise (AWGN) channel, the performance of the proposed DCDLL scheme is about 1.4 dB better than that of one-correlator tau–dither loop (TDL), and near that of noncoherent DLL.)
