ABSTRACT:
The
presence of systematic measuring errors complicates track-to-track association,
spatially separates the tracks that correspond to the same true target, and
seriously decline the performances of traditional track-to-track association
algorithms. Consequently, the influence of radar systematic errors on tracks
from different radars, which is described as some rotation and translation, has
been analyzed theoretically in this paper. In addition, a novel approach named alignment-correlation
method is developed to estimate and reduce this effect, align and correlate tracks
accurately without prior registration using phase correlation technique and statistic
binary track correlation algorithm. Monte-Carlo simulation results illustrate
that the proposed algorithm has good performance in solving the track-to-track
association problem with systematic errors in radar network and could provide
effective and reliable associated tracks for the next step of registration.
