摘要

An optimum solution to the time delay detection and tracking problem for a single signal is extended to the multisignal problem where the number of signals present in the observed data (if any) is unknown. The number of signals present is determined, and the time delay of each detected signal is tracked. The number of possible global, or first level, hypotheses is large because of the exponential dependence on the number of potential signals. An efficient approximate multisignal detection and tracking solution that is as near optimum as possible for the computational resources required is developed. It has the form of parallel detector-trackers (one for each potential signal) each similar to the single-signal case, with communication between them. Test results demonstrate the utility of the approach.
