Identifying Radar Emissions

This project was undertaken under contract to DSTO Salisbury during 1985 and 1986. The aim of the project was to assist Electronic Support Measures officers on board ships to identify the type of radar illuminating the ship from another platform. The radar type can suggest the kind of platform and whether it is a threat or not. A method of belief revision based on an assumption-based truth maintenance system (ATMS) was developed. This enabled us to reason with incomplete and uncertain evidence for hypotheses.
