保卫感兴趣的地区，无论是陆地、海洋还是空中，抵御无数入侵者，例如无人系统（空中、海上和陆地），对已经紧张的边境保护系统提出了一系列严峻的挑战。敌人的复杂性和商业可用技术允许入侵系统迁移到检测到弱点的区域。随着入侵事件在各地区的潮起潮落，我们的应对措施也必须同样熟练地转移到这些地区。此外，这些边境保护系统必须具有成本效益并且能够适应不断变化的环境。在这种情况下，我们提出了一组低成本、自主、小型无人机系统（sUAS），能够运输到当前的活动热点，成群发射，持续数小时至数天，为人工在环操作提供实时反馈，并可在以后检索以供重复使用。我们注意到，感兴趣的目标能够以两种不同的模式运行：射频主动模式和射频被动模式。在射频主动模式下，目标通常以相当连续的方式与操作员进行通信。在射频无源模式下，目标通过内部导航飞行到特定位置。我们的方法是为小型无人机系统配备廉价而有效的电子设备，以使用到达时间差（TDOA）、到达频率差（FDOA）和到达频率差（FRDOA）技术对两种类型的目标（即射频主动和被动）进行协作地理定位和跟踪。向指挥中心提供轨迹信息，使他们能够决定要采取的行动。
Defending an area of interest, whether land, sea or air, against a myriad of intruders, e.g., unmanned systems (air, sea and land), poses a serious set of challenges to an already stressed border protection system. Enemy sophistication and commercially available technologies allow the migration of intrusion systems to move to areas where weaknesses are detected. Our response must be equally adept at moving to the areas as intrusion events ebb and flow over regions. Additionally these border protection systems must be cost effective and adaptable to changing environments. In this case, we propose a fleet of low-cost, autonomous, small Unmanned Aerial Systems (sUAS) with the ability to be transported to current hotspots of activity, launched in swarms, persistent for hours to days, provide real-time feedback for man-on-the-loop operations, and be retrievable for reuse at a later time. We note that the targets of interest are able to operate in two distinct modes: RF active and RF passive. In the RF active mode the target is typically communicating with an operator in a rather continuous fashion. In the RF passive mode the target is flying via internal navigation to a specific location. Our approach is to equip the sUASs with inexpensive yet effective electronics to perform cooperative geolocation and tracking of both types of targets, i.e., RF active and passive, using Time Difference of Arrival (TDOA), Frequency Difference of Arrival (FDOA) and Frequency-Rate Difference of Arrival (FRDOA) techniques. Providing the track information to the command center allowing them to decide actions to be taken.
