Abstract:

The purpose of the research was to study the application of dynamic tuning, if practically feasible, to the design of a particular signal sorter in order to improve its performance. A simulation model of a signal sorter in a dense environment, which was studied and developed through work by the Advanced Techniques Branch of the TEW Division of the NRL was used for problem analysis. Signal sorting involves the correlation of the mass of signals detected by a receiver with the individual sources that generate each signal. Identification of particular emitters necessitates maintenance of a file to compare received pulses with those currently identified or known to be in a particular environment and to update when new emitters are detected in the environment. The signal sorter generates these files based on parameters measured by the receiver, such as direction-of-arrival DOA, carrier-frequency, pulse-width and latest time-of-arrival, and generated parameters based on measured parameters, such as pulse-repetition-interval PRI.
