Target Motion Analysis Based on Peak Power Measurements using Networked Sensors

Target motion analysis (TMA) using a network of wireless sensors/receivers which measure the power from a mobile RF emitter is considered. Due to limited communication capability of each sensor node, only peak power measurements from sensor nodes are transmitted to the fusion center. We present two...

Zusammenfassung:Target motion analysis (TMA) using a network of wireless sensors/receivers which measure the power from a mobile RF emitter is considered. Due to limited communication capability of each sensor node, only peak power measurements from sensor nodes are transmitted to the fusion center. We present two main results that yield the optimum sensors' configuration such that the asymptotically achievable error variance of the target trajectory's estimate is minimized, and we derive efficient numerical algorithms for computing the optimum estimates of the trajectory of the moving target, thus achieving the goal of TMA.
