摘要
采用分数阶傅里叶变换来计算目标回波多普勒频率,然后依据牛顿迭代法来求解标量脱靶量。仿真结果表明,该方法较FFT算法精度高,效果更好。
The target echo signal Doppler frequency is calculated by using Fractional Fou- rier Transform（FRFT）, and then the scalar miss distance is solved by using Newton ittrative method. Simulation results show that the FRFT algorithm is better than the FFT algorithm.
