This paper proposes a target tracking algorithm using asynchronous TDOA (Time Difference of Arrival) and FDOA(Frequency Difference of Arrival) measurements for a single target in a distributed sensor network. A conventional algorithm, target localization through TDOA measurements cannot estimate target position when the number of TDOA measurements are not enough for localization at the same time....
Focusing on nonlinear/non-Gaussian filters and based on analysis of the sampling-importance-resampling algorithm, this paper examines principles and application of particle filter (PF) in satellite orbit determination. There may be large error of initial estimation and non-Gaussian distribution of state and measurement in satellite orbit determination. To solve the two problems, an improved PF algorithm...
