The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed coordinated positioning algorithm based on ionospheric virtual height (IVH) model jointly estimate target position and reflection using direction of arrival (DOA) time difference (TDOA) measurements. method is divided into two stages, first stage ...

This paper develops the model of joint phantom track deception and techniques time-difference arrival (TDOA) frequency-difference (FDOA) localization to deceive air defense radar networks under condition that an unmanned aerial vehicle (UAV) swarm has no prior knowledge radars’ precise locations, related performance experiment analysis are presented demonstrate effectiveness proposed method cla...

Estimating time-difference-of-arrival (TDOA) remains a challenging task when acoustic environments are reverberant and noisy. Blind channel identification approaches for TDOA estimation explicitly model multipath reflections and have been demonstrated to be effective in dealing with reverberation. Unfortunately, existing blind channel identification algorithms are sensitive to ambient noise. Th...

Abstract A closed‐form solution for localising and synchronising an acoustic sensor node with respect to a Wireless Acoustic Sensor Network (WASN) is presented. The aim allow efficient scaling of WASN by individually calibrating newly joined nodes instead recalibrating the entire array. key contribution that be calibrated does not need include built‐in emitter. proposed method uses signals emit...

The US Federal Communications Commission (FCC) has mandated wireless network operators and mobile devices to provide accurate location information for E-911. Requirements for time of arrival (TOA) and time difference of arrival (TDOA) measurements have been specified in 3GPP LTE Rel. 9 to ensure accurate user equipment (UE) positioning even under bad conditions (e.g. with channel quickly varyin...
