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))

说明：  首先确定被评价对象的因素（指标）集和评价（等级）集；再分别确定各个因素的权重及它们的隶属度向量，获得模糊评判矩阵；最后把模糊评判矩阵与因素的权向量进行模糊运算并进行归一化，得到模糊综合评价结果(Firstly, the factor (index) set and the evaluation (grade) set of the evaluated object are determined; then the weight of each factor and their membership degree vectors are determined separately, and the fuzzy evaluation matrix is obtained; finally, the fuzzy evaluation matrix and the weight vector of the factor are fuzzily calculated and normalized, and the result of the fuzzy comprehensive evaluation is obtained.)
