Simulation of Track Fusion of Airborne ESM and Radar
Ren Qing-an · Radar Science and Technology · 2012
Electronic support measures(ESM) and active radars have already become the most important sensors on airborne platform for acquiring target information.A multi-parameters model based on a series of simulation computations for track fusion of airborne ESM and active radar is proposed in this paper,including track registration,track correlation and track fusion.The time-space registration based on coordinate transform and interpolation is mainly considered for track registration.For track correlation,three track correlation algorithms are well analyzed,which are based on statistic,fuzzy analysis and fast judgment separately.A fast linear weighting fusion method is given for track fusion.In the experiment,an evaluation method for track correlation algorithms is proposed and a comparison between three track correlation algorithms with different parameters is given.The results have also shown that the fusion precision is better than that of active radar or ESM.Finally,several constructive conclusions are made for practical engineering applications.
