摘要
雷达-目标径向加速度是表征雷达和目标相对运动关系重要特征,可用于机动目标跟踪、目标识别等,因此研究直接从雷达回波估计径向加速度很有必要.本文给出了基于Wigner-Hough变换的径向加速度估计算法和算法实现流程,并分析了接收回波信号时长对加速度最小可分辨单元的影响,最后进行了仿真试验,仿真结果证实了该算法的有效性.
Radial acceleration of radar and target is a important character of the relative movement of them and can enhances maneuvering target tracking and target identification, so study on radial acceleration estimation directly from radar echo is needed. The algorithm of estimating radical acceleration is derived, estimation flow is provided, and the impact of observation interval on radial acceleration resolution is analyzed. Then simulation is carried out and results verify its efficiency.
