粒子图像分割及匹配均为自行编制的子例程，基于分段非线性权重值的Pso算法，表示出两帧图像间各个像素点的相对情况，有较好的参考价值，通过虚拟阵元进行DOA估计，线性调频脉冲压缩的Matlab程序。-Particle image segmentation and matching subroutines themselves are prepared, Based on piecewise nonlinear weight value Pso algorithm, Between two images showing the relative circumstances of each pixel, There are good reference value, Conducted through virtual array DOA estimation, LFM pulse compression of the Matlab program.
