Motivated by target tracking of OTHR inevitably facing the problem of multiple propagation modes, we present the problem of joint multipath data association and fusion (JMAF). Based on the expectation-maximum criterion and joint optimization, we derive the iterative optimization scheme of multipath data association and track fusion. A performance comparison of multipath probability data association...
Considering the fact that target tracking of the sky wave Over-The-Horizon Radar (OTHR) inevitably faces the problems of multipath, low detection probabilities et al., we make use of the advantage of avoiding data association and low computational cost for Gaussian mixture probability hypothesis density (GM-PHD) filter and propose a multipath GM-PHD (MP-GM-PHD) filter framework. Such framework is...
Target tracking of sky wave OTHR inevitably faces the problem of multiple propagation modes, through modeling target movement in ground coordinate and implementing data association in radar coordinate, a multipath viterbi data association (MVDA) algorithm is proposed, which extends viterbi data association (VDA) from association between measurement and track to association among measurement, propagation...
In this paper, a data preprocessing method for sky-wave over-the-horizon radar (OTHR) track initiation using two-hierarchical 2D Hough transform is proposed. We firstly use range-time data space to hierarchical I Hough transform and obtain rough candidate measurement sequences, where Doppler is used as an accumulation constraint; then we use the corresponding azimuth and time measurements to hierarchical...
