机载平台径向加速度的无模糊相差检测

Detection of Radial Acceleration on Airborne Platform by Measuring Phase Difference Without Ambiguity

由径向加速度的数学定义,通过对距离与相移之间的函数进行二次微分即可获得基于相差变化率测量的径向加速度解析表达式,进一步利用相差变化率的无模糊检测方法即可得到径向加速度的无模糊相差检测解。

According to mathematical definition, the analytic expression of radial acceleration based on measuring phase difference rate can be obtained by quadratic differential for the function between radial distance and phase shift. More, using the method of measuring phase difference rate without ambiguity, the solution of radial acceleration based on phase difference measuring without ambiguity can be obtained.
