等间距线性阵列，阵元间距d= λ /2，等幅加权，目标方位φr = 0°，无噪声。 分别仿真计算阵元数M=8 、16时的阵列方向图，定性分析产生的原因。（可通过3dB波束宽度计算公式说明） (Equally spaced linear array, the array element spacing d = λ/2, equal amplitude weighted target azimuth φr = 0, no noise. , Respectively, the number of array elements M = 8 and 16 when the array pattern, qualitative analysis to produce simulation. (Available by 3dB beamwidth formula noted))

matlab程序，计算时间差，爱好matlab编程的可以下载(matlab program to calculate the time difference, love can download matlab programming)

基于随机有限集的单目标以及多目标跟踪文章以及代码(RFS Multi-target tracking PHD Filter)

用改进蚁群算法求解一类连续空间优化问题的matlab实现(improved ant colony algorithm for solving a class of continuous space optimization problems achieving Matlab)

谱估计的welch算法的matlab仿真(Spectrum estimation welch algorithm matlab simulation)

太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)

实现通信中SDPSK调制和解调的matlab源程序(Realize communication SDPSK modulation and demodulation matlab source)

该程序是基于小波变换的熵谱，用来提取时间序列的周期成分。熵谱相对于小波谱来说在提取周期成分上有一定优势(The program is based on spectral entropy of wavelet transform to extract time series of the periodic component. Entropy is relative to the small spectral component in the extraction cycle, there are some advantages)
