用于条带式合成孔径雷达（SAR）成像仿真的MATLAB程序，可直接运行。(MATLAB program for the strip of synthetic aperture radar (SAR) imaging simulation can be run directly.)

通过pch文件提取nastran质量矩阵、刚度矩阵，需要更改文件名称和自由度数（dof）,生成质量矩阵、刚度矩阵M,K(Extraction of mass matrix, stiffness matrix of NASTRAN)

matlab中线性不等式LMI工具箱的使用，中文版(matlab LMI toolbox in the use of linear inequalities)

Scott (1992) lead to better large sample performance of the histogram.

说明：  Cachy分布，产生cachy 分布的概率密度，随机数(Cachy distribution)

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
