惯性导航，利用惯性元件（加速度计）来测量运载体本身的加速度，经过积分和运算得到速度和位置，从而达到对运载体导航定位的目的。组成惯性导航系统的设备都安装在运载体内，工作时不依赖外界信息，也不向外界辐射能量，不易受到干扰，是一种自主式导航系统。(Inertial navigation, to measure the carrier itself acceleration Inertial element (accelerometer), through integration and operation to get the speed and position, so as to achieve the purpose of vehicle navigation. Inertial navigation systems equipment components are installed in the carriage of the body, does not rely on external information work, not to the outside world-radiation energy, less susceptible to interference, it is an autonomous navigation system.)

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)

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))
