An algorithm for Doppler Rate-of-change Estimation from Coherent Pulses of a Sinusoidal Signal

研究了正弦相参脉冲信号多普勒变化率的估计问题.利用相参脉冲之间相位相参的特性,提出一种最小二乘估计算法.仿真实验证实了该算法的正确性,精度基本达到Cramer-Rao限,以及对时变多普勒变化率测量的有效性.

This paper is concerned with the estimation of Doppler rate-of-change from the characteristics of coherent pulses of a sinusoidal signal in additive Gaussian noise. With phase coherence considered, a least square algorithm is proposed. Simulation experiments prove that the algorithm is effective and performs near Cramer-Rao bound, and suitable to time variable Doppler rate-of-change.
