Track initiation algorithm based on Hough transform is an effective method on condition of strong clutter environment. But due to the influence of measurement error and the selection of parameter space threshold, the problems of clutter points mix in target tracks and multiple tracks initialized by only one target are existed. In order to solve these problems, this paper proposes a track initiation...
For the issue of maneuvering target tracking when existing oppressive jamming whose polarization is unfixed, on the basis of information fusion of multi-sensors, we combine the technique of polarize agility and waveform agility to process the signal and data to achieve the target detecting, SCR rising and tracking precision improving. On the one hand, waveform agility can improve the measuring precision...
The problem of track association with systematic error between radar networks is researched. ECEF (Earth-centered-Earth-fixed) coordinate is taken as the common reference coordinate, and multi threshold is used to carry out track association. The coarse threshold is based on the different sensors' measurement. The sampling variance that obtained by sequence error is taken as the history track correction...
In OTHR's tracking system, we will estimate the state of a discrete-time, linear stochastic system whose observation process consists of a finite set of known, non-linear measurement models. MPDA is capable of exploiting multipath target signatures arising from discrete propagation modes that are resolvable by the radar, but it is very time-consuming and will bring multipath tracks. In this paper,...
