Paper Abstract

The objective of this paper is to examine the performance of the sequential approach and an asynchronous data fusion approach to target tracking as defined for two dissimilar sensors. First, analytical expressions for evaluating the performance of these two approaches were derived. Then, these expressions were applied to the fusion of data from a multi-tasking radar and an optical sensor. It is assumed that the data rate of the optical sensor is much higher than the radar's. Overall, it was found that the sequential and data fusion approaches have reasonably similar performance for this case. However, the computational advantage of the fusion approach makes it more attractive than the sequential approach.
