Although numerous algorithms have been proposed for TDOA-based localization, these algorithms are not suitable for media where the transmitter signal propagation speed is not known and is variable due to the presence of a non-homogenous medium. For example, an electrical signal transmitting through the heart tissue will have a differential velocity, and also it is unknown during Afib. In a forest fire, the fire propagation speed can vary due to wind direction and velocity. During a tsunami, wave velocity can be differential due to the effect of the difference in underwater topology. In this project, we design algorithms to solve for the target location along with the signal propagation speed.
Work will include algorithms validation on simulated data; data collection and algorithm validation on data; and visualization tasks. Deliverables include data sets, code, update presentations in weekly meetings, final report, and presentation at RAPS.
