A Bayesian approach to predicting an unknown number of targets based on sensor performance
Estimating remaining targets after some attempt has been made to detect an overall, unknown number of targets is critical to determining the potential threat associated with these remaining targets. This paper presents a Bayesian approach tocalculate the distribution on the number of remaining targets given the sensor performance and thenumber of targets detected. For a single sensor, a closed form posterior distribution on remaining targets is derived. For multiple sensors, the correspondingposterior distribution is developed. A naive implementation of this calculation is shown to be computationally prohibitive, and an efficient means for performing the calculation is presented.
