Target tracking algorithm for passive coherent location
Aleksandr A. Konovalov · IET Radar Sonar & Navigation · 2016
A target tracking algorithm for the passive coherent location based on a two‐stage scheme is proposed and implemented. The track initiation, the tentative track filtering and the data association for all tracks are performed in bistatic coordinates using a linear decoupled Kalman filter. The confirmed track filtering is performed in Cartesian coordinates by non‐linear unscented Kalman filtering. Transformation of the measurements and their covariances from bistatic to Cartesian coordinates and vice versa are implemented via unscented transformation for 2 n sigma‐points.
