For the problem of multi-path effects, firstly the low-angle target tracking model of sea-surface is built up, and the geometric relationship among target, image and radar is analyzed.

针对多径效应的问题，首先建立海面低空目标的跟踪模型，分析了目标、镜像和雷达之间几何关系。

The Adaptive Warehouse target model automatically embeds a prompt expression in queries which evaluate the time context for history tracking dimension attributes.

Adaptive Warehouse目标模型自动嵌入一个提示表达式到查询中，该查询为历史跟踪维度属性评估时间上下文。

Both tracking methods achieve the target tracking state in common by establishing the motion parameter model and obtaining the motion state estimation of the target.

这两种方法的共同点是都是通过建立目标运动的参数模型，获得目标的运动状态估计，从而实现目标跟踪。
