Abstract
Sensor data fusion has long been recognized as a means to improve target tracking. Common practice assumes that the sensors used are synchronous, i.e., they have identical data rate, measurements are taken at the same time, and have no communication delays between sensors platform and central processing center. Such assumptions are invalid in practice. Previous work of the authors dealt designing asynchronous track fusion filter that removes such assumptions when considering the multi-sensor target tracking case. This paper deals with the existence of a solution to the asynchronous track fusion problem for the case of two asynchronous sensors. In addition, the performance deterioration of the filter is analyzed as a function of the track fusion update rate.
