基于混沌扰动算法来解决pso算法早熟问题，并用二者结合来训练灰色预测模型参数(Perturbation algorithm based on chaotic algorithms to solve the pso early-maturing issues, and to use a combination of both to train the gray prediction model parameters)

使用matlab编写的图像特征提取软件，可对图像进行批量处理(Written using the image feature extraction matlab software, batch processing of images)

采用geese算法对采样的阵列信号进行处理，根据阵列结构上存在的差异进行估计，采用标准差的方式进行估计。geese算法性能的好坏 (Geese algorithm on sampled array signal processing, according to an estimate of the differences that exist on the array structure, estimated using standard differential manner. the geese algorithm performance quality)

利用Matlab软件编程实现DDS（直接数字频率合成技术）。设时钟的频率为固定值f_C，在CLK的作用下，如果按照0000,0001,0010，…，1111的地址顺序读出ROM中的数据，即表1中的幅值编码，其正弦信号频率为f_01；如果每隔一个地址读一次数据（即按0000,0001,0100，…，1110顺序），其输出信号频率为f_02，且f_02将比f_01提高一倍，即f_02=2f_01；其余类推。这样，就可以实现直接数字频率合成器的输出频率的调节。(Matlab software programming DDS (direct digital frequency synthesis). Clock frequency set to a fixed value f_C, under the effect of CLK, according to 0000,, ..., 1111 of the sequence of addresses in the ROM reads the data, i.e., the amplitude of the encoding in Table 1, the frequency of the sinusoidal signal f_01 if every time a read address data (ie 0000,0001,0100, ..., the order of 1110), the output signal frequency is f_02, and f_02 f_01 than doubled, i.e. f_02 = 2f_01 rest on. This allows direct digital frequency synthesizer output frequency regulation.)
