Low elevation sea-surface target tracking using IPDA type filters

The integrated probabilistic data association (IPDA) type filters provide estimates of the underlying target probability of existence/perceivability/visibility, apart from track state maintenance. These quantities are conveniently used as a track quality measure and can be used for track confirmation and termination. The sea-surface induced multipath fading reduces the detection probability of the target at certain ranges, which can lead to track loss. In this paper, we use IPDA type filters for tracking a target in such a scenario. The primary results presented in this paper are encouraging for a further study in the future.
