Electromagnetic (EM) source localization has become a vital issue lately to improve civilian safety, increase the military security and mitigate the disaster effect. The localization is embedded in battle-field surveillance, traffic alert, emergency call 911 (E911), resource allocation and mitigation of disaster effect. The location of the emitter can be determined by bestowing its transmitted ...

The resilience of indoor localization systems is a main concern their industrial application. A combination different techniques can enhance the overall robustness such systems. In this work, we present fusion possibilities coarse Bluetooth Low Energy based on received signal strength indicator and finer ultrasound time difference arrival (TDOA) technique. This approach offers advantage to robu...

The location of an emitter is estimated by intercepting its signal and sharing the data among several platforms to measure the time-difference-of-arrival (TDOA) and the frequency-difference-of-arrival (FDOA). Doing this in a timely fashion requires effective data compression. A common compression approach is to use a rate-distortion criterion where distortion is taken to be the mean-square erro...

Time synchronization and localization are key requirements for distributed underwater systems consisting of numerous low-cost submersibles. In these systems, submersibles are highly resource constrained and typically have limited acoustic communication capability. We investigate the problem of tracking submersibles that only have the capability of receiving acoustic signals. Traditional Long Ba...

The steered response power phase transform (SRP-PHAT) is a beamformer method very attractive in acoustic localization applications due to its robustness in reverberant environments. This paper presents a spatial grid design procedure, called the geometrically sampled grid (GSG), which aims at computing the spatial grid by taking into account the discrete sampling of time difference of arrival (...

] Abstract: An effective way to locate RF transmitters is to measure the time-difference-of-arrival (TDOA) and the frequency-difference-of-arrival (FDOA) between pairs of signals received at geographically separated sites, but this requires that samples of one of the signals be sent over a data link. Often the available data link rate is insufficient to accomplish the transfer in a timely manne...

In many passive localization applications, the reference waveform of received electromagnetic signals is partly known. The in such scenarios are formulated by modelling relationship between data and known signal parameters interest, as time-difference-of-arrival (TDOA) frequency-difference-of-arrival (FDOA). By exploiting prior information carried signal, negative impact random noise can be sig...
