A simple sensor management criterion for radar beam control based on the CB-MeMBer filter

The cardinality balanced multi-target multi- Bernoulli (CB-MeMBer) filter has received a lot of attention as a good approximation to the ideal multi-target filter. Consequently, several schemes have been proposed in order to perform sensor management when a CB-MeMBer filter is used. Most of these criteria are computationally very expensive due to the nature of the CB-MeMBer filter and the integration over the measurement space that is necessary for hedging against all possible measurement realizations. In this paper we present a simple sensor management criterion that has trivial computational complexity and performs at least as well as the other sensor management schemes that can be found in the literature. We demonstrate the behavior of our proposed criterion in a radar beam-pointing problem where several targets are tracked.
