Prior velocity and acceleration distributions are often applied in one point initialization, where the track state is initialized based on a single measurement. This distribution is often approximated by a (first two moments preserving) Gaussian distribution. These parameters are derived as a function of the problem dimensionality and target trajectory assumptions.
This paper presents an effective recursive tracking method for the single mobile emitter using correlated TDOA measurements. In multiple-sensor environment the time difference of arrival (TDOA) measurements are correlated. We consider only the case of single emitter tracking without data association issues, e.g., no missed detection or false measurements. We describe a scenario of three static receivers...
