摘要
针对连续波雷达测速过程中目标径向加速度对速度测量精度的影响,采用基于自相关函数与先验知识相结合的方法进行加速度估计和补偿。仿真试验结果表明,该方法能够有效地估计出目标的径向加速度,先验知识的引入进一步降低了正确估计对输入信噪比的要求,提高了估计精度,减小了计算量。
Aiming at the influence of target radial acceleration on velocity measuring precision in CW radar, an acceleration compensation and estimation method based on auto correlation function and priori knowledge is presented. The simulation results verify that the method can estimate the radial acceleration efficiently, and the use of priori knowledge can reduce the requirement of SNR, improve the precision of estimation and lower its computational cost.
