基于主动目标的FMCW雷达定位系统具有利基短程应用，其包括船舶和其他船只停泊的海上导航以及避开诸如石油钻井平台的障碍物。对于这些类型的系统，目标回波的衰减速率大于背景杂波，从而使得目标检测困难。本文探讨了一种基于目标内雷达回波频移的技术，该技术用于将接收到的目标回波的位置转换到更高的频率，从而大大降低杂波。它示出，通过一个合适的设计和仿真，这种方法可以很容易地被用来实现在这些类型的定位系统的更大的操作范围。
Active target based FMCW radar location systems have niche short range applications which include maritime navigation with the berthing of ships and other vessels and avoiding obstacles such as oil rigs. For these types of systems the target return decays at a greater rate than the background clutter, thus making target detection difficult. In this paper, a technique is explored, based on frequency shifting the radar echo within the target, which serves to translate the position of the of the received target return to a higher frequency where the clutter is greatly reduced. It is shown, by means of a suitable design and simulation, that this approach may readily be used to achieve a much greater operating range in these types of location systems.
