Joint multipath data association and fusion for OTHR

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 (MPDA) is presented and discussed for a simple target tracking scenario, and the simulation results show that JMAF is superior to MPDA.
