strech
去斜率(strech)参考信号与回波信号混频后得到中频输出信号S(t)=Aexp(j*2*pi*f0*t+phase)
其中f0与回波延时的关系为:
f0=k*delay_t
K为线性调频斜率,delay_t为回波延时
将s(t)采样,FFT变换即可得到目标距离与频谱的关系。
Strech 信号测距
输入混频后的中频信号(图一),经采样及FFT变换得到频谱(图二)
再根据频谱与距离的关系式R=Tcf/2B显示出距离(图三)
(Go slope (strech) obtained after the reference signal and the echo signal mixer IF output signal S (t) = Aexp (j* 2* pi* f0* t+phase) f0 and echo delay relationship: f0 = k* delay_t K chirp slope, delay_t the echo delay sampling s (t), the FFT transform to the target distance spectrum of relations. Strech signal ranging input mixer IF signal (Figure 1), sampling and FFT transform spectrum (Figure 2) according the the spectrum distance relationship R = Tcf/2B shows the distance (Figure 3))

Topology_Optimization_a_99_line
Ole Sigmund编写的99行Matlab程序是拓扑优化方面的经典案例。该程序有5个可修改的输入参数:竖直方向网格划分数nely,水平方向网格划分数nelx,保留的材料的体积分数volfrac,惩罚因子penal和滤波器大小rmin。加载方式矩阵F和支承方式fixeddofs也可以分别选取不同的方式或组合。(Ole Sigmund prepared by the 99-line Matlab program is a classic example of topology optimization. The program has five can modify the input parameters: the number of vertical mesh nely, the number of horizontal mesh nelx, keep the volume fraction of material volfrac, penalty factor penal and filter size rmin. Loading mode and the supporting means fixeddofs matrix F can also be selected separately or combined in different ways.)
