摘要
提出了一种差分多普勒信息在目标速度估计中的应用方法,并给出了具体的算法。对差分多普勒信息应用于目标速度估计中的精度进行了理论分析,通过Monte carlo仿真对提出的算法进行了验证。仿真结果表明,利用差分多普勒信息能够有效地提高对目标速度的估计精度,并且对目标机动段也能够取得很好的速度估计精度。
An application method of new estimator using FDOA to estimate the target velocity is proposed and its concrete algorithm is presented. The precision of the velocity estimation with this method is theoretically analyzed and the algorithm is validated by Monte Carlo simulation. The simulation result shows that a better estimation velocity than the Kalman filtering especially for the maneuvering target can be achieved by using FDOA.
