摘要通过一组装有全向接收信号强度(RSS)传感器的无人飞行器，研究了具有间歇传输的射频(RF)发射机的定位问题。这个小组开始了一个自主巡逻，以指定的准确性，尽可能快地定位和跟踪目标。这一挑战可以分解为两个阶段：1）给定先前测量的目标位置估计（定位）；2）给定当前估计（路径规划），规划跟踪无人机的未来轨迹以获得较低的期望定位误差。对于每一阶段，我们从性能和计算负载两个方面比较了两种算法。在定位阶段，我们比较了基于检测的扩展卡尔曼滤波(EKF)和递归贝叶斯估计器。在路径规划阶段，我们比较了最速下降后Cramer-Rao下界(CRLB)路径规划和一种仿生启发式路径规划。我们的结果表明，最速下降路径规划比仿生路径规划的性能好一个数量级，而递归贝叶斯估计器仅比基于检测的EKF的性能好一个数量级。

英文摘要：
  Localization of a radio frequency (RF) transmitter with intermittent transmissions is considered via a group of unmanned aerial vehicles (UAVs) equipped with omnidirectional received signal strength (RSS) sensors. This group embarks on an autonomous patrol to localize and track the target with a specified accuracy, as quickly as possible. The challenge can be decomposed into two stages: 1) estimation of the target position given previous measurements (localization), and 2) planning the future trajectory of the tracking UAVs to get lower expected localization error given current estimation (path planning). For each stage we compare two algorithms in terms of performance and computational load. For the localization stage, we compare a detection based extended Kalman filter (EKF) and a recursive Bayesian estimator. For the path planning stage, we compare steepest descent posterior Cramer-Rao lower bound (CRLB) path planning and a bio-inspired heuristic path planning. Our results show that the steepest descent path planning outperforms the bio-inspired path planning by an order of magnitude, and recursive Bayesian estimator narrowly outperforms detection based EKF.
