使用迭代算法对运动目标进行分割，阈值可以自适应调节(Using an iterative algorithm for moving target segmentation threshold can adaptively adjust)

用Shepard方法实现散乱数据的曲面拟合(Shepard method using surface fitting of scattered data)

Designs a linear phase FIR lowpass filter such that it: - minimizes the filter order - has a constraint on the maximum passband ripple - has a constraint on the maximum stopband attenuation (This is a quasiconvex problem and can be solved using a bisection. minimize filter order n s.t. 1/delta <= H(w) <= delta for w in the passband |H(w)| <= atten_level for w in the stopband where H is the frequency response function and variable is the filter impulse response h (and its order/length). Data is delta (max passband ripple) and atten_level (max stopband attenuation level). )

关于随机共振中的非线性平行阵列的程序，提供了多种非线性模型的仿真(About nonlinear stochastic resonance in a parallel array of procedures, provides a variety of nonlinear model simulation)

说明：  GDOP(Geometric Dilution of Precision) 几何精度因子是衡量一个定位系统精度的重要标准之一。 运行程序sGDOP.m可得到三站GDOP仿真结果，更改程序中s_x,y,z可以更改阵列的几何排列。运行程序fGDOP.m得到四站GDOP仿真结果。(GDOP (geometric division of precision) geometric accuracy factor is one of the important standards to measure the accuracy of a positioning system. Running the program sgdop. m, we can get the simulation results of three stations GDOP, and changing the geometry of the array by changing the program s _ x, y,z. Running the program fgdop.m, the simulation results of four stations GDOP are obtained.)
