| 摘 要： | 利用超宽带穿墙雷达跟踪运动目标在军事和民用领域的应用日益广泛.目标运动参数估计和位置矫正是超宽带穿墙合成孔径雷达(UWB TW-SAR)对运动目标跟踪的两大关键部分.针对传统方法只能对匀速运动目标参数估计的不足,研究了一种基于乘积型高阶模糊度函数(PHAF)算法的加速运动目标参数估计新方法,并分析了墙体折射对运动目标聚焦位置的影响,对目标运动轨迹进行矫正.仿真结果证明了该方法能较准确地估计加速运动目标参数并实现目标的跟踪.

| Abstract: | Tracking moving targets behind walls with ultra wideband trough-wall radar has important application value in military and civil areas.Parameter estimation and position correction for moving targets are two key issues in moving target tracking with through-wall UWB synthetic aperture radar(UWB TW-SAR).Traditional methods can only estimate the parameters of moving targets with constant speed.To overcome the shortcoming of traditional methods,a new method is investigated for the parameter estimation of accele... |
