| 摘 要： | 本文在分析了线性调频信号距离-多普勒耦合和脉冲压缩原理的基础上,提出了一种单个脉冲混合信号条件下径向速度测量的新方法.该方法将频域上互不重叠的调制脉冲进行时域叠加,通过脉冲压缩的频率选通特性,得到不同距离-多普勒耦合系数下的距离信息,再根据距离-多普勒耦合偏差的计算公式建立方程组,求解获得了目标的径向速度,解决了高耦合系数条件下多普勒耦合测距误差修正、航迹关联以及航迹起始的问题.对导弹防御雷达的仿真验证了该方法的有效性.

| Abstract: | On the basis of such principle as LFM range-Doppler coupling and pulse compress,a new method of radial velocity measurement using single pulse is presented.Pulses which are not frequency overlapped are composed temporally.And through frequency selection characteristics of pulse compress,different range information in condition of different range-Doppler coefficient is obtained.The radial velocity is then obtained through the equation group constructed using the range information.The method solves such problems as range-Doppler modification,data association and trajectory construction for the case of high coupling coefficient.The simulation result of missile defense radar verifies the efficiency. |
