1) low-angle targets
低仰角目标
1.
Aiming at the problem that the performance of target elevation estimation gets worse due to the influence of multipath effects in low-angle tracking for meter-wave radars,this paper presents a new method of elevation estimation for low-angle targets by canceling reflected waves through the analysis of the multipath model of multi-scattering centers of low-angle targets for meter-wave radars.
针对米波雷达低仰角跟踪目标过程中,由于多路径效应引起的目标仰角估值性能变差这一问题,该文通过对米波雷达低仰角目标多散射中心多路径模型的分析,提出一种基于反射波对消的低仰角目标角度估值方法。
2) low-altitude target measurement

1.
Accoring to the feature of low elevation target moving along fixed airway,the paper establishes the echo model for the target moving in the direction of the mid-point of the baseline by geometric analysis and discusses the applicability and accuracy limitation of the model.
利用几何分析的方法,针对低空固定航路目标的特点,建立了目标沿双基地系统基线中点方向运动的回波信号模型,并对模型的适用范围和精度进行了分析,为建立双站系统对低仰角固定航路目标的模糊函数及其监测性能分析提供了一条新思路。
